Brake Noise When Braking Slowly – Possible Reasons And Solutions

by Jordan Harris
Brake Noise When Braking Slowly

One of the most common complaints always reported by drivers is that they often hear brake noise when braking slowly. Such sounds as scraping, squealing, and squeaking may lead to vibrations, especially noise when braking at a low speed.

When your brakes are not functioning properly, they are one of the most perceptible parts of your car in terms of the sound they make. Brakes are prone to making sounds, but when you start noticing a high-pitched squealing or squeaking sound when you use them even at low speeds, that’s a clear sign something is not okay and ought to be addressed.

In this article, we’re going to learn the 15 common causes of brake noise when braking slowly and the possible solutions to the problem. For each of these reasons, we’ll also look into the respective symptoms. As well as, how to properly diagnose and troubleshoot these issues. In addition, understanding what you can do to fix this for good.

How Does The Braking System Work

The braking system is a car’s most significant safety tool. The system has various parts with which it works toward achieving a similar goal – To stop the wheels of the vehicle and hence stop the car. Every brake works under the principle of friction.

Opposing force is something friction does, but we increase it using brakes. Friction converts the kinetic energy into heat, which eventually brings the vehicle to a halt. All vehicles have brakes on all four wheels that are operated by a hydraulic system.

The brakes are either a drum or disc type. Most vehicles have four-wheel disc brakes, however, others have drums for the rear wheel and discs for the front wheels. But since the massive responsibility of stopping a car relies on the front brakes, the more effective disc brakes are installed on the front wheels.

The brake system works in various ways. When you hit the brake pedal, the force generated by your leg is amplified numerous times by mechanical leverage. It’s then amplified more by the action of the brake booster. The piston enters the cylinder and squeezes the hydraulic fluid out of the end.

Hydraulic fluid is then distributed around the whole braking system within a system of brake hoses and lines. Afterward, pressure is then distributed equally to all the brakes. The force generated generates friction between the disc brake rotors and brake pads, which stops the car.

During this process, you may hear brake noise when braking slowly, which in most cases points to a defect in one of the braking elements.

Different Types Of Odd Brake Noises

Before we jump into the causes and solutions, understanding various brake noises will help you gauge the severity of a brake problem. Learn what grinding, scraping, and squeaking sounds signify.

Brake Noise When Braking Slowly, Noise Types #1: Brake Grinding

Grinding noise from the braking system is a red flag; it’s always a serious problem. Grinding brake noise when braking slowly means that all your car brakes are used up. The only thing left is the rotor and the caliper. The minute you notice your car brakes grinding at low speed, stop your vehicle

Immediately head on to the nearest service center for help. If you leave your brakes to grind before servicing them, you’ll be left in a worse situation. The repair will be more costly.

Brake Noise When Braking Slowly, Noise Types #2: Squealing

Squealing brake noise when braking slowly is often a result of parking your car outdoors in a wet area. When metal surfaces get in touch with water for a long period, they start to develop rust. And that’s the case here.

However, after driving for some time, the rust diminishes. And after a few brakes, the creaking sound when braking slowly might even disappear. Nevertheless, it isn’t a good idea to park your car in a wet area.

Brake Noise When Braking Slowly, Noise Types #3: Squeaking

Squeaking sound often results from low-quality brake pads. You see, low-quality brake pads have huge metal flakes in them. So, it comes in contact with the rotor, hence producing noise. Always opt for quality brake pads in the first place.

Besides that, the moment you hear the sound, it means your rotor is constantly getting damaged. The brake’s wear indicator will let you know when you need to change your brake pads.

Brake Noise When Braking Slowly

Now that you’re aware of the types of noises, let’s delve right into the reasons to help you figure out the right solution.

Brake Noise When Braking Slowly, Common Reasons #1: Worn Out Brake Pads

One of the common reasons for brake noise when braking slowly is having worn-out brake pads. Brake pads are manufactured from a mixture of copper, iron, and graphite. All these things are bonded together to form a brake pad. But with time, they get worn out.

That’s when the outer metal of the rotor and the clipper comes in contact, resulting in the said noise. So, if you’ve used your brake pads for a long time or have worn them, go and change them immediately. Failure to do so will result in severe damage to your brakes. Besides, the caliper and the backing plate can destroy each other, causing grooves and damage.


When your brake pads are wearing thin or are already worn out:

  • You might hear a constant grinding or screeching noise when braking, especially at lower speeds.
  • The car may take longer to come to a complete stop.
  • The brake pedal may vibrate or feel softer than usual.
  • A warning light might illuminate on the dashboard.


Brake pads wear out due to:

  • Continuous friction between the pads and the rotor over time.
  • Driving conditions that demand frequent braking, like heavy city traffic.
  • Use of low-quality brake pads that aren’t durable.
  • Heavy braking habits by the driver.

Diagnosis and Troubleshooting

  1. Visual Inspection: Lift the car and remove the wheel. Look at the brake pads. If there’s less than 1/4 inch of the pad visible, it’s time for a replacement.
  2. Listen: Worn-out pads often produce a high-pitched squealing sound.
  3. Brake Pedal Feel: If the pedal feels soft or goes further to the floor than usual, the pads may be worn.
  4. Warning Light: Some modern cars have sensors that alert the driver when the brake pads are wearing thin.

DIY Fixes and Repairs

  1. Brake Pad Replacement:
    • First, ensure your car is on a flat surface. Use a jack to raise the car.
    • Remove the tire to access the brakes.
    • Locate the caliper, slide it out, and remove the old brake pads.
    • Push the piston back, place the new brake pads, and reassemble the caliper.
    • Reattach the tire, lower the car, and ensure the brakes feel firm when pressed.
  2. Preventive Maintenance:
    • Regularly inspect your brake pads.
    • Avoid aggressive driving and sudden stops.
    • Use high-quality brake pads designed for your car model.
    • Rotate and align wheels periodically.

Repair/Replacement Cost

  • Parts: Depending on your vehicle’s make and model, a brake pad set can cost between $30 to $250.
  • Labor: A mechanic might charge anywhere from $100 to $300, depending on location and vehicle type.

Brake pads are essential for safety, and timely maintenance ensures a longer lifespan for other brake components and a safer driving experience. Always prioritize timely replacements to prevent larger, more costly issues down the road.

Brake Noise When Braking Slowly, Common Reasons #2: Moisture In The Brake Assembly

Occasionally, you may notice that your car brakes squeal after rain or on a particularly humid morning when you start driving. That’s usually caused by moisture in the brake assembly, around the rotor and brake pad. Water may inevitably get in there eventually, but if it’s not affecting your brake’s performance, just the sound it makes, it may not be a cause for concern.

If it happens more often and even during mornings when it’s not moist, then you may have a problem that ought to be addressed. When it happens, it results in the formation of a thin layer of rust around the rotor. Upon applying brakes, the thin layer of rust is scraped off as rusty debris, which ends up being the source of squeals in your brakes.


When moisture affects the brake assembly:

  • A squealing or grinding noise might be audible when you brake.
  • This noise is particularly noticeable in the morning or after the car has been stationary in humid conditions.
  • You might notice a slight resistance or “drag” the first few times you apply the brakes after the car has been exposed to moisture.


The presence of moisture in the brake assembly can be attributed to:

  • Environmental factors such as heavy rainfall, dew, or fog.
  • Infrequent use of the vehicle, allowing moisture to accumulate.
  • Parking in damp locations or areas prone to water pooling.
  • Brake components are not sealed properly, allowing water intrusion.

Diagnosis and Troubleshooting

  1. Visual Inspection: Check the brake rotor for signs of rust. If there’s visible rust that wipes off easily, it’s likely moisture-induced.
  2. Driving Test: Drive the vehicle slowly and apply the brakes multiple times. If the noise disappears after a few stops, the moisture might have evaporated.
  3. Check Surrounding Areas: Ensure wheel wells, mudguards, and drainage points are clear of debris that might trap moisture.

DIY Fixes and Repairs

  1. Rust Removal:
    • Safely lift the car using a jack.
    • Remove the wheel to expose the brake components.
    • Use a fine-grade sandpaper to gently rub off the rust from the rotor’s surface.
    • Wipe the rotor with a clean cloth and reassemble it.
  2. Preventive Maintenance:
    • Try to park your car in a dry place, especially during wet seasons.
    • After driving through water or in heavy rain, gently tap your brakes a few times to disperse moisture.
    • Use brake parts cleaner spray occasionally to clear debris and prevent moisture buildup.

Repair/Replacement Cost

  • Parts: If parts like rotors or pads need replacement due to excessive rust damage, it can range between $30 to $250, depending on vehicle make and model.
  • Labor: A mechanic may charge $50 to $200 for inspection and rust removal, based on the extent of rust and location.

Moisture-induced brake noises are common and often harmless, but it’s essential to ensure they don’t signal deeper rust issues or compromised brake efficiency. Regular check-ups and maintenance can prevent long-term complications.

Brake Noise When Braking Slowly, Common Reasons #3: Presence Of Dirt And Debris

Just like water finds its way into the braking system, so do foreign substances like dust, dirt, grease, etc. Brake pads, calipers, and rotors are frequently exposed to dirt and dust from the road surface. These contaminants get trapped between the brake pad and rotor surfaces, causing a hissing or squealing brake noise when braking slowly.

The build-up of foreign substances on the braking surface may also increase the amount of force the pads apply to the rotors when braking. If this happens, it can lead to sticky, noisy brakes, especially at low speeds when the temperature of brake pads is higher than usual.

A small amount of rust on the rotor surface is expected if the vehicle has been parked for a few days and often wears out rapidly upon the application of brakes a few times at high speeds. However, the rust may stay on the rotors even longer if the brakes are only applied at lower speeds.


When debris gets into the braking system:

  • There may be a persistent squealing, hissing, or grinding noise when braking.
  • Brake response might feel inconsistent or jittery.
  • The brake pedal could feel harder or stickier than usual.
  • You might experience vibrations when braking.


The intrusion of debris into the brake assembly can be due to:

  • Driving on dusty roads or areas with lots of loose gravel.
  • Neglecting regular cleaning and maintenance of the wheel and brake areas.
  • Driving through muddy areas or puddles, which can introduce dirt and contaminants.
  • Use of inferior brake components that produce excessive dust.

Diagnosis and Troubleshooting

  1. Visual Inspection: With the wheel removed, check the brake components for visible dirt, dust, or grease. The rotor should look clean and metallic.
  2. Braking Test: Drive the car at various speeds and apply brakes. Note if the noise changes or disappears at higher speeds.
  3. Brake Pad Inspection: Check for excessive wear or uneven pad wear, which can be a sign of debris-caused friction.

DIY Fixes and Repairs

  1. Cleaning:
    • Elevate the car safely using a jack.
    • Remove the wheel to access the brake system.
    • Use a brake cleaner spray to clean the rotors, pads, and calipers thoroughly. Make sure to wear safety goggles and a mask.
    • Let the components dry and reassemble.
  2. Preventive Maintenance:
    • Frequently wash your car, especially the wheel wells, to remove contaminants.
    • Avoid driving through large puddles or muddy terrains.
    • If possible, choose routes with less dust or debris.
    • Always use high-quality brake components that produce minimal dust.

Repair/Replacement Cost

  • Parts: If significant wear or damage is caused by debris, new brake pads or rotors might be required. This can range from $30 to $250 depending on the vehicle.
  • Labor: Mechanics may charge $50 to $200 for a thorough cleaning and inspection, depending on the severity of the debris buildup.

Driving conditions significantly affect brake cleanliness. While debris-caused noises might seem minor, they can decrease braking efficiency. Regular inspections and cleanings are crucial for optimal brake performance.

Brake Noise When Braking Slowly, Common Reasons #4: Broken Brake Shims

These are basically metal adhesive or thin rubber that sit between the caliper and the brake pads to eliminate any sounds. Therefore, it’s pretty apparent what happens when the shims get broken.

A worn-out shim will make contact with a piece of the braking system, such as the rotor. When there is a metal-to-metal contact like this, you’ll hear a grinding sound from your braking system. So, anytime you get a brake job done, make sure to replace the shims.


When you’re dealing with broken or damaged brake shims:

  • A distinct grinding or metal-on-metal noise can be heard during braking.
  • The braking performance might feel less responsive or efficient.
  • There may be increased vibration felt through the brake pedal.
  • A decrease in overall braking efficiency may be noticed, taking longer distances to come to a complete stop.


Brake shims can wear out or get damaged due to:

  • Excessive heat is generated during aggressive braking.
  • Continuous friction from regular braking over time.
  • Using low-quality or mismatched brake pads and shims.
  • Improper installation or positioning during a brake service.

Diagnosis and Troubleshooting

  1. Visual Inspection: With the wheel removed, closely inspect the brake shims for signs of wear, cracks, or misalignment.
  2. Sound Identification: If the noise is a distinct metal-on-metal grinding sound, it may point towards a shim problem.
  3. Brake Test: Apply the brakes at varying speeds. Damaged shims may produce noise more consistently across all speeds.

DIY Fixes and Repairs

  1. Brake Shim Replacement:
    • Safely elevate the car using a jack.
    • After removing the wheel, detach the brake caliper to access the brake pads and shims.
    • Remove the old or broken shims and replace them with new ones, ensuring proper alignment.
    • Reassemble the caliper and the wheel, then test the brakes for any noises.
  2. Preventive Maintenance:
    • Use quality brake pads that come with or are compatible with good shims.
    • Regularly inspect the braking system for wear and tear.
    • Ensure brake jobs are done by experienced professionals to guarantee proper shim placement.

Repair/Replacement Cost

  • Parts: New brake shims are relatively inexpensive, often ranging from $10 to $50, depending on the vehicle’s make and model.
  • Labor: Mechanics could charge between $50 to $150 for inspection and shim replacement, contingent on the specific vehicle and labor rates in your area.

Regular inspections and replacements of brake shims are critical, not only for a quiet braking experience but also for safety. Ensuring that these components are in good condition can prevent more costly repairs down the line.

Brake Noise When Braking Slowly, Common Reasons #5: Low-Quality Brake Pads

These are just minor annoyances. They aren’t necessarily an indicator of an issue with the brakes. Your brakes will still work fine when these sounds occur; it’s just the kind of annoyance to deal with. Other low-quality brake pads are made with high-quality metal content.

It’s important to note that most brake pads have some degree of metal in them, but the cheaper ones have large quantities, which can easily damage your rotors with time. When the metal entrenched in the pad material squeezes against the rotors, you will probably hear a squealing sound, especially when slowing down, which can potentially last the entire life period of the pad.

When you want to replace your brake pads, you ought to make sure you are focused on the ones with more organic material. Resin, rubber, fiber, Kevlar, and so on are all materials that make up a brake pad and are less annoying and damaging in terms of producing sounds you don’t want to hear.

If the problem persists, you could have the issue recalibrated, and a mechanic could possibly disassemble the assembly and change the harmonics. That may seem a risky path to take, but if the problem is bad enough, you may want to consider it.


When using low-quality brake pads:

  • A high-pitched squealing sound is frequently observed during braking.
  • You may feel vibrations in the brake pedal.
  • The braking might feel less smooth or consistent.
  • Premature wear and tear on the rotor due to the higher metal content.


Low-quality brake pads become problematic due to:

  • Excessive metal content which can be abrasive against the rotor.
  • The absence of adequate organic materials like resin, rubber, and Kevlar that dampen noise.
  • Poorly bonded materials which can break down faster under heat and pressure.

Diagnosis and Troubleshooting

  1. Visual Inspection: Check the brake pads for signs of excessive wear or metal glints.
  2. Auditory Identification: Pay attention to the specific sounds. Metal-heavy brake pads often produce a sharper, consistent squeal.
  3. Performance Test: Note the braking performance. Cheaper pads might provide inconsistent braking.

DIY Fixes and Repairs

  1. Brake Pad Replacement:
    • Safely elevate the car using a jack.
    • Remove the wheel to access the brake caliper.
    • Detach the caliper to remove the brake pads.
    • Install new, high-quality brake pads with more organic material content.
    • Reassemble the brake system and test for noise.
  2. Preventive Maintenance:
    • Always opt for brake pads that have a balanced mixture of materials, favoring organic content.
    • Regular brake system inspections can catch wear early, helping you decide when to replace it with quality parts.

Repair/Replacement Cost

  • Parts: High-quality brake pads can range from $50 to $200, depending on the brand and the vehicle model.
  • Labor: Mechanics might charge between $100 to $300 for brake pad replacement, depending on your location and the complexity of the job.

Investing in high-quality brake pads not only ensures a quieter driving experience but also prolongs the life of your braking system. While initial costs may be higher, you’ll likely save money in the long run by avoiding frequent replacements and potential rotor damage.

Brake Noise When Braking Slowly, Common Reasons #6: Worn Out Rotor Discs

Worn-out rotor discs may result from braking using low-quality or worn-out brake pads, which scratch the rotor surface. After a while, the flat surface of the rotor will be distorted, hence causing a squeaking sound. Rotor discs that are extensively worn out may form scraping sounds instead.

Another reason for deflecting the rotor surface is washing your vehicle and exposing the rotors to cold water when it’s still hot. This leads to the deflection of the surface, and you’ll hear noise and vibrations when braking. These vibrations occur in irregular forms and can easily be felt through the brake pedal.


With worn-out or distorted rotor discs:

  • A pronounced squeaking or scraping sound is emitted during braking.
  • Vibration or pulsation can be felt through the brake pedal.
  • Braking performance can deteriorate, leading to increased stopping distances.
  • Uneven brake pad wear might be observed due to irregular rotor surfaces.


The following can lead to rotor disc wear:

  • Use of low-quality or excessively worn brake pads that scratch and erode the rotor surface.
  • Exposing hot rotors to cold water, causing sudden temperature changes that lead to warping or deflection.
  • General wear and tear over prolonged periods of use.
  • Aggressive or heavy braking which generates excessive heat.

Diagnosis and Troubleshooting

  1. Visual Inspection: Examine the rotor surface for visible signs of wear, scratches, or warping.
  2. Brake Performance Test: Pay attention to any uneven braking or extended stopping distances that might indicate rotor issues.
  3. Vibration Assessment: Feel for consistent or irregular vibrations through the brake pedal when braking.

DIY Fixes and Repairs

  1. Rotor Resurfacing:
    • Elevate the car safely.
    • Remove the wheel and brake caliper to access the rotor.
    • Using a rotor lathe, resurface the rotor to make it smooth again.
    • Reassemble the brake system and test for any persistent issues.
  2. Rotor Replacement:
    • Follow the steps above, but instead of resurfacing, replace the old rotor with a new one.
  3. Preventive Maintenance:
    • Avoid spraying cold water on hot brake components.
    • Use quality brake pads to minimize rotor wear.
    • Regularly inspect and maintain the braking system.

Repair/Replacement Cost

  • Parts: A new rotor can cost anywhere from $30 to $250, depending on the vehicle model and quality.
  • Labor: Mechanics might charge between $100 to $400 for rotor replacement or resurfacing, contingent on the region and job complexity.

Regularly inspecting and addressing issues with rotor discs can greatly improve your vehicle’s safety and performance. Whether resurfacing or replacing, it’s crucial to address rotor problems promptly.

Brake Noise When Braking Slowly, Common Reasons #7: Faulty Wheel Bearing

When you hear noises or vibrations from your wheels that alternate from quiet to loud, you probably have a damaged or worn-out wheel bearing. Therefore, carefully check the wheels and replace them if need be to avoid annoying sounds.


When dealing with a damaged or worn-out wheel bearing:

  • A humming, roaring, or growling noise that increases in volume as the vehicle accelerates.
  • Uneven tire wear can be observed due to wobbling.
  • Looseness or play in the wheel when off the ground.
  • Vibrations are felt in the steering wheel, especially when cornering or braking.
  • An ABS light might illuminate if the bearing is integrated with the wheel speed sensor.


Factors leading to wheel bearing wear or damage include:

  • Normal wear and tear over extended periods of driving.
  • Poor road conditions or hitting potholes and curbs.
  • Corrosion due to water exposure, particularly from floods or deep puddles.
  • Overloading the vehicle beyond its recommended weight limit.

Diagnosis and Troubleshooting

  1. Noise Identification: Listen for humming or growling noises that intensify with speed.
  2. Physical Check: With the car lifted, wiggle the tire. Any play can indicate a worn bearing.
  3. Driving Test: Take note of vibrations or changes in noise when turning. Faulty bearings might be more apparent during cornering.

While wheel bearing issues might not directly relate to the brake system, they can influence overall driving safety and comfort. Addressing them early prevents additional damage and ensures smooth driving.

Brake Noise When Braking Slowly, Common Reasons #8: Car Left Unattended

When a car remains parked for extended periods, especially in humid or damp areas, rust can develop on its metal components, including the braking system. The accumulation of rust on brake rotors can generate a squeaking sound when brakes are applied at slower speeds.

As the brake pads make contact with the rusted rotors, this noise becomes noticeable. Over time, the consistent use of brakes can help scrub off the rust. Yet, excessive rust can hamper the braking efficiency, so it’s essential to inspect and address any rust build-up.


When rust accumulates on brake components due to prolonged inactivity:

  • A noticeable squeaking or grinding sound occurs during braking.
  • Reduced braking efficiency might be felt, requiring more force to stop the car.
  • Visible rust patches or a thin layer of rust on the brake rotors.
  • In extreme cases, the brake pedal might feel spongy or less responsive.


The following situations can lead to rust accumulation on brakes:

  • Parking in humid, damp, or coastal areas where moisture levels are high.
  • Not using the vehicle for extended periods.
  • Leaving the car exposed to rain or other wet conditions without driving it afterward.

Diagnosis and Troubleshooting

  1. Visual Inspection: Check the brake rotors for visible signs of rust. Light brown or reddish spots are typical indicators.
  2. Braking Test: Apply brakes at various speeds and listen for squeaking or grinding noises.
  3. Brake Response: Assess the responsiveness of the brake pedal, checking for any unusual feelings.

DIY Fixes and Repairs

  1. Removing Surface Rust:
    • Safely elevate the car.
    • Use sandpaper (around 120-grit) to gently scrub away visible rust on the rotors. Ensure you maintain an even pressure to avoid creating grooves.

Leaving cars unattended for long durations can lead to numerous maintenance issues, including brake rust. Addressing this early ensures safety and preserves the vehicle’s value. Regular use and proper storage are key to prevention.

Brake Noise When Braking Slowly, Common Reasons #9: Caliper Pin Issues

Caliper pins are essential for guiding brake pads into the correct position. If these pins get jammed, the brake pad may not contact the disc adequately, causing a groaning sound when braking slowly. Regular inspection and lubrication of these pins can prevent such issues, ensuring optimal braking performance and reducing the risk of unwanted noises.

In addition to that, failure to lubricate the caliper screws and bolts causes a grinding brake noise when braking slowly. This hardly occurs, but it could. If it happens, ask your mechanic to replace the caliper bolts for you.


When facing issues with caliper pins:

  • A groaning or grinding sound is heard when braking slowly.
  • The brake pads may wear unevenly or prematurely.
  • Reduced braking efficiency, making the car harder to stop.
  • Brake pads might stick, causing continuous light contact with the rotor even when brakes aren’t applied.


The common factors leading to caliper pin issues include:

  • Lack of periodic lubrication leading to pins getting jammed or sticking.
  • Accumulation of dirt, dust, or road debris around the pins.
  • Natural wear and tear over time.
  • Use of substandard or incorrect lubricants.

Diagnosis and Troubleshooting

  1. Visual Inspection: With the car safely elevated, inspect the caliper pins for visible signs of wear, dirt, or corrosion.
  2. Braking Test: Apply brakes at various speeds and listen for groaning or grinding noises.
  3. Movement Test: Check the movement of the brake pads; sticking or jammed pads indicate pin issues.

DIY Fixes and Repairs

Regular maintenance of caliper pins is crucial for optimal braking performance. Using the right lubricant and addressing issues promptly will ensure safe and noise-free braking.

Brake Noise When Braking Slowly, Common Reasons #10: Loosely Tightened Wheel

After brake pad installations, improperly tightened lug nuts can lead to unwanted brake noises. A loosely tightened wheel may wobble when brakes are applied, creating a groaning sound. This wobbling can also hasten the wear of brake pads. It’s critical to ensure wheels are securely fastened after any brake maintenance.


When facing issues with a loosely tightened wheel:

  • A groaning, creaking, or clanking sound when braking.
  • Noticeable wobbling or shaking of the car, especially at high speeds.
  • Uneven tire wear due to misalignment from the wobble.
  • The brake pedal might feel uneven or pulsating when pressed.


The common reasons for a wheel being loosely tightened include:

  • Inadequate torquing of lug nuts after tire changes or brake work.
  • Using incorrect tools or torque wrench settings during wheel installation.
  • Omitted lug nuts or the use of damaged or corroded nuts.
  • Overlooking the final tightening step after vehicle lifting.

Diagnosis and Troubleshooting

  1. Visual Inspection: Examine the wheel for any obvious gaps or misalignments.
  2. Shake Test: With the car safely elevated, grab the tire at the 3 and 9 o’clock positions and shake it. If there’s a noticeable give, the wheel might be loose.
  3. Torque Test: Using a torque wrench, check the tightness of each lug nut against the manufacturer’s recommendations.

DIY Fixes and Repairs

  1. Tightening the Wheel:
    • Safely elevate the car, ensuring it’s stable.
    • Using a torque wrench, tighten each lug nut in a star pattern to the manufacturer’s recommended setting. This ensures even pressure.
    • It’s crucial not to over-tighten, as this can warp brake rotors or damage lug nuts.
  2. Inspect Lug Nuts:
    • Check for signs of wear, corrosion, or thread stripping on each lug nut.
    • Replace any damaged lug nuts immediately.
  3. Preventive Maintenance:
    • Whenever the wheels are removed, always re-torque lug nuts to the proper specifications.
    • Periodically check the tightness of lug nuts, especially after visiting a mechanic or tire shop.

Repair/Replacement Cost

  • Parts: Replacing lug nuts can cost anywhere from $5 to $20 each, depending on the make and model.
  • Labor: If taken to a professional, checking and tightening a wheel might cost from $20 to $50, depending on the shop’s hourly rate.

Ensuring wheels are securely fastened is not only crucial for quiet braking but also for overall vehicle safety. Regularly checking lug nut tightness can prevent many potential issues.

Brake Noise When Braking Slowly, Common Reasons #11: Brake Rotor and Pad Bedding

New brake rotors and pads might produce groaning sounds when braking at low speeds. This can be attributed to the lack of proper bedding, where the brake pads and rotors haven’t yet adjusted to each other. Bedding, done by repetitively applying brakes from various speeds, can help create a consistent friction surface, minimizing noise and enhancing performance.


For vehicles with newly installed brake rotors and pads, the following may be observed:

  • Groaning or squealing noises when braking at low speeds.
  • Reduced brake responsiveness or a “soft” feeling in the brake pedal.
  • A noticeable smell, akin to burning, emanating from the brakes after driving.


The noises and issues stem from:

  • Friction Variability: New pads and rotors may not have uniform friction surfaces initially, leading to noise.
  • Transfer Layer Absence: Effective braking requires the brake pad material to deposit a thin layer onto the rotor. New components might not have established this transfer layer yet.

Diagnosis and Troubleshooting

  1. Visual Inspection: Check the surface of the rotors. Uneven coloration or noticeable spots can be indicative of improper bedding.
  2. Braking Test: While driving in a safe environment, apply brakes from various speeds. If inconsistencies or noises lessen over time, the bedding process is underway.

DIY Fixes and Repairs

Maintaining the health of control arm bushings ensures smoother rides and reduced noise when braking. Regularly inspecting and addressing any issues promptly can prevent more expensive suspension system repairs down the road.

Brake Noise When Braking Slowly, Common Reasons #15: Ceramic Brake Pads

The type of material that your brake pads are made of has a significant impact on the noise produced by your brakes when you apply them. Since brakes need to absorb a lot of friction, they should handle substantial heat over time. Asbestos was once the desired choice for brake lining but was phased out because it was carcinogenic and hence dangerous to use.

When asbestos was eliminated, other materials came into play, including Kevlar, ceramics, and other metal blends. Kevlar can be dusty and sometimes lead to squeaking sounds in the brakes. However, other metals and ceramics used can also result in such sounds as squealing, grinding, and hissing.

While ceramic brake pads are durable and produce less dust, they might produce more noise, especially when cold. Since they aren’t as good heat conductors as metallic pads, they might not be suitable for every vehicle. Ensuring the right brake pads are chosen for a particular vehicle type can help avoid braking noises.

Brake pads are a crucial component in a vehicle’s braking system, responsible for creating the friction that slows down the wheels. The materials used in these pads can significantly influence both their performance and the sounds they make during operation.


  1. Temperature Sensitivity: Ceramic brake pads often produce more noise when they are cold. As they warm up, the noise might reduce, but the initial noise upon starting can be noticeable.
  2. Material Hardness: While ceramics are known for their durability and long lifespan, they are harder than other brake pad materials. This hardness can lead to more pronounced noise, especially in certain driving conditions or when paired with specific rotor types.
  3. Less Heat Conduction: Unlike metallic brake pads, ceramics don’t conduct heat as efficiently. This can sometimes lead to squealing or hissing sounds during braking, especially during prolonged usage or intense driving conditions.

Pros & Cons

Despite the potential for noise, ceramic brake pads offer several advantages:

  1. Less Brake Dust: Ceramic brake pads produce finer, lighter-colored dust that doesn’t stick to wheels, keeping them cleaner.
  2. Durability: Ceramic brake pads tend to have a longer lifespan compared to other materials, offering extended intervals between replacements.
  3. Consistent Performance: Ceramics offer consistent braking performance, especially in regular driving conditions.

Fixes & Solutions

  1. Appropriate Pairing: Ensure that ceramic brake pads are matched with suitable rotors, which can help reduce noise.
  2. Break-in Period: New ceramic brake pads might require a break-in or bedding-in period to seat properly and reduce noise.
  3. Regular Inspection: If the noise persists, it might be a sign of uneven wear or other issues that require attention.
  4. Lubrication: Proper lubrication of brake components can help reduce noise caused by vibration.

While ceramic brake pads are appreciated for their benefits, potential noise issues should be considered. Ensure the pads are suitable for your specific vehicle and driving conditions to optimize performance and minimize unwanted sounds.

Diagnosis Of Brake Noise Problems

If you experience brake noise problems with your car, it’s important to diagnose the problem yourself even before taking it to an auto repair shop. Here are various ways to perform some checks to ascertain the source of the problem.

Brake Noise When Braking Slowly, Diagnosis Step #1: Find Loose Parts

The initial step is to take apart your car’s front wheels. Perform a simple check by shaking the rotor, pads, calipers, and other brake components. All these parts shouldn’t be moved by hand. If there are any vibrations, there are a few loose, damaged, or missing bolts and clips. You ought to fix that immediately. Failure to do so leads to even more vibrations and noise braking.

Brake Noise When Braking Slowly, Diagnosis Step #2: Apply Dampening Paste

Extreme vibrations from braking parts often lead to lousy brake noise when braking slowly. After fixing the loose or damaged bolts or clips, you will want to apply damping paste – a water-based compound extremely effective in reducing noises and vibrations from your braking parts.

Apply the dampening paste on the metal part of the brake pad (at the back of it) between the caliper piston and the brake pad. Allow the paste a significant amount of time to dry (between 2 to 3 hours or till it dries off completely) before you reassemble the brake unit. This enables it to become sticky and darker.

Brake Noise When Braking Slowly, Diagnosis Step #3: Examine The Brake Shoe Or Brake Pads

Examine the brake pads for replacement or wearing out. Most drivers find this quite challenging when driving. Most brake pads have a wear indicator designed to alert you when it’s worn out. Since aftermarket brake pads come in different sizes, they tend to wear out unevenly.

This, in turn, makes the pad ride the edge of the rotor resulting in logical brake noise so you can hear noise while braking, but the pads are in good condition. In that case, you can smoothen the lip and make it even to increase the brake pad’s lifespan and get rid of the noise. If it means having to replace your brake pad, make sure to get the correct pad. New brake pads can make noise as well until the pads are at the rotor surface shape.

Brake Noise When Braking Slowly, Diagnosis Step #4: Examine The Brake Rotor

When using your car and changing the brake pad, your rotors may be affected by this process. It may result in an uneven brake rotor, causing the brake pad to jump and wiggle. You ought to have an extremely smooth rotor surface. Therefore, if the rotor wear is not that profound, you may be prompted to have your rotors machined to smoothen the surface.

Make sure to check your rotor’s thickness before performing this procedure because it may affect your braking’s safety. But if the wear is extreme or the whole rotor isn’t thick or is distorted, you will have to replace the rotors immediately.

Brake Noise When Braking Slowly, Diagnosis Step #5: Conduct An Extra Check

It’s always important to check the brake lines and the brake oil after conducting maintenance on your braking system. Check its level, and if it’s below the marked level, you need to fill the right oil up to the marked level.

Besides, also ensure to check your brake fluid color. If it is anything else apart from bright and clear, then you need to change it as soon as possible. Probe for any signs of leakage in the brake line and if you happen to locate one, replace it immediately.

Brake Noise When Braking Slowly

Brake Repair Cost

Sometimes, the brake noise may become unbearable or make you feel like it’s causing a decrease in your overall brake performance. In that case, it’s advisable to get your brakes repaired. Even if they aren’t faulty, the sound generated can be so annoying to justify having your pads replaced.

The cost of replacing your pads goes per axle. Therefore, you would generally replace either the back brakes or the front brakes at the same time. You could do it all at once, but that will hike the price.

The average cost of replacing brake pads typically ranges between $150 to $300 per axle. However, this may vary significantly according to the type of brake pads you’re using. Ideally, better brake pads cost an average of $30 or more, depending on the material used.

Just like any other repair job, you can repair your brakes if you wish to. For instance, changing the brake pads isn’t a difficult task if you’re comfortable working on your vehicle’s repair. You need to keep in mind that there are various causes for squeaking in your brakes and just problems with the pads.

There are also numerous guides online, such as the one below, that can help walk you through a detailed process of repairing your brakes, so you know exactly what you need and ensure you don’t miss anything.

Can You Repair Your Own Brakes

You need to ensure that you have jack stands, a floor jack, and a brake to get the job done. It also helps to properly position the brake caliper piston to the new brake pads. It’s also vital to make sure that the brake pads are accurately fixed when switching to the new ones.

You don’t want pads that are just installed and don’t correctly fit or adjusted, as this may lead to clamping down of the pads on the rotor when pressing the brakes with your foot. However, this is one of the rare tools used, and many people who don’t spend most of their time doing brakes lack one of these in their toolbox despite its cheap price.

Most drivers are dreaded by the idea of fixing their own brakes because of the fear that they may do something wrong, and the brakes are the last thing you want to fix wrongly. In that case, there’s no harm whatsoever in getting your car to an auto repair shop for repair rather than trying it on your own.

There are certain things you need to consider when fixing your brakes. So if you are not comfortable performing this fixture, you should leave it to the experts that you can count on to ensure nothing goes wrong.

Brake Maintenance

Maintaining your car is a bold step toward saving money rather than taking your vehicle to an auto repair shop only when an issue arises.

Why Does It Sound Like Air When I Press the Brake Pedal

A sound like air when pressing the brake pedal often indicates a problem with the brake booster or its vacuum system. The brake booster uses an engine vacuum to assist the braking force. If there’s a leak in the system or the brake booster is failing, you might hear a hissing or air-like sound when pressing the pedal. It’s essential to address this issue to maintain effective braking.

Why Does My Car Shake When I Brake at Low Speed

If your car shakes when braking at low speeds, it often points to a problem with the brakes. One common reason is warped rotors. Over time, or due to excessive heat, the rotors can become uneven, causing the brake pads to grip inconsistently. Another possible cause is unbalanced tires or issues with the suspension components. Regular inspection and maintenance can help address this issue.

Why Are My Brakes Screeching

Brakes screech primarily because of worn-out brake pads. Most brake pads have a built-in wear indicator that creates a high-pitched screeching sound when the pads are due for replacement. Other causes can include debris or rust between the brake pad and rotor, misaligned components, or the use of low-quality brake pads.

What Do Bad Brakes Sound Like

Bad brakes can produce various sounds. A high-pitched squeal often indicates worn-out brake pads. A grinding sound suggests that the pads are completely worn, and the metal backing is rubbing against the rotor. Rumbling or thumping sounds might be due to damaged rotors, while a clicking noise can indicate a problem with the brake assembly. Addressing these sounds promptly ensures safety and prevents further damage.

Why Does My Car Rattle When I Brake

A rattling sound when braking can be due to loose or damaged brake hardware, such as the caliper or brake pad retaining clips. Brake pads might also rattle if they’re not fitting snugly within the caliper. Besides the brakes, issues with suspension components or loose undercarriage parts can also cause rattling when braking.

What Removes Brake Dust from Rims Home Remedies

A mixture of baking soda and water can effectively remove brake dust. Mix three parts baking soda to one part water to create a paste. Apply this mixture to the rims, scrub gently with a brush, and then rinse off. Another remedy is using a solution of equal parts white vinegar and water. Spray it on the rims, let it sit for a few minutes, scrub, and rinse. Always ensure the rim is cool to the touch before cleaning.

Where to Get Brakes Done Cheap

To get brakes done at an affordable rate, consider local independent mechanics or auto schools where students work under the supervision of experienced instructors. Additionally, some chain auto repair shops offer promotional deals. Always ensure that even if you’re looking for affordability, the quality of service and parts isn’t compromised.

Why Is My Brake Pedal Squeaking

A squeaking brake pedal usually indicates a problem with the pedal assembly or related components. The pivot points of the brake pedal might need lubrication, or there could be wear in the bushings or springs. A failing brake booster can also cause squeaking sounds. Regular inspection and maintenance can help pinpoint and address the root cause.

What Causes Brakes to Lock Up While Driving

Brakes can lock up due to various reasons. A seized brake caliper, deteriorated or collapsed brake hoses, or issues with the brake master cylinder can all cause brakes to lock up. In some cases, a malfunctioning anti-lock brake system (ABS) can also be the culprit. Locked brakes are a serious issue and should be addressed immediately to ensure driving safety.

Are New Brakes Supposed to Squeak

No, new brakes are not typically supposed to squeak. However, some initial noise may occur during the bedding-in process, where the brake pads and rotors adjust to each other. If the squeaking persists, it could be due to improper installation, misaligned components, or the use of low-quality parts.

Why Do My Brakes Sound Crunchy

A crunchy or gritty sound from brakes can be due to debris, sand, or small rocks caught between the brake pad and rotor. This can cause a grinding noise during braking. Additionally, if brake components are corroded or heavily rusted, it can produce a crunchy sound. It’s essential to inspect and clean the brakes to avoid further damage.

Why Are My Brakes Still Grinding After Replacing Pads and Rotors

If brakes are still grinding after replacement, it could be due to improper installation or misalignment of the new components. Another reason could be the presence of debris or foreign materials between the pads and rotors. Sometimes, incompatible or low-quality parts can also lead to grinding noises. It’s crucial to have the brakes inspected to identify the root cause.

What Does a Bad Caliper Sound Like

A bad caliper can produce various sounds. A squeaking or squealing noise can occur if the caliper sticks and causes the brake pads to drag. A grinding noise might be heard if the caliper isn’t releasing properly, leading to constant contact between the pad and the rotor. Additionally, a bad caliper can cause a clunking noise, especially if its mounting hardware is loose or damaged.

Will Loose Lug Nuts Cause Noise

Yes, loose lug nuts can cause noise. When lug nuts are not properly tightened, the wheel can wobble, leading to a clicking or clunking sound, especially during driving or braking. Loose lug nuts are a serious safety concern, and if suspected, the vehicle should be stopped, and the lug nuts should be checked and tightened immediately.

Which Brake Pads Wear Out First

Typically, the front brake pads wear out faster than the rear ones. This is because the front brakes handle a higher percentage of the braking load, especially in front-heavy vehicles. However, the wear rate can vary based on driving habits, vehicle weight distribution, and brake system design.

How to Press Wheel Bearings Without a Press

If you don’t have access to a press, you can use a large socket that matches the size of the outer bearing race and a hammer to carefully tap the bearing into place. Ensure the bearing is aligned correctly. Once aligned, tap it gently and evenly, ensuring it seats properly. Using a piece of wood between the hammer and socket can help distribute the force and reduce the risk of damaging the bearing. However, using a press is the preferred method as it provides even pressure and reduces the risk of installation errors.
