Why Do New Ceramic Brake Pads Make Grinding Noise [Causes & Solutions]

Ceramic brake pads have become the first choice due to their durability and excellent performance. However, you may experience that new ceramic brake pads are making grinding noise. It is a must to remove that issue to continue safe and smooth driving. But how to fix new ceramic brake pads make grinding noise?

You should check for worn brake pads and repair or replace them if they are worn. Next, check for their alignment and ensure it is okay. Also, ensure the brake calipers and rotors are in good working order. Finally, ensure there is no lubrication issue; if you find poor lubrication, lubricate it to remove the problem.

You need more than just telling about the causes and solutions; you need more depth detail about them. Stay with me and learn in detail how to fix the new ceramic brake pads that make grinding noises. Let’s get started.

Causes Of Grinding Noise In Ceramic Brake Pads

Grinding noise from new ceramic brake pads can be due to many reasons. However, I am mentioning a few major common issues for such noises for a quick solution. You must check for this issue to fix the problem.

• Worn brake pads
• Misaligned brake pads
• Rusted brake rotors
• Damaged brake caliper
• Insufficient lubrication

Signs and Symptoms Of Ceramic Brake Pads Making Grinding Noise

Grinding Noise:

The audible sound is one of the most prominent signs of ceramic brake pads making a grinding noise. When the brakes are applied, a grinding or scraping noise can be heard. It may happen due to worn down or damaged brake pads.

Reduced Braking Performance: 

Another symptom is a noticeable decrease in braking performance. You may feel your vehicle takes longer to stop or requires more force on the brake pedal.

Vibration or Pulsation:

A vibrating or pulsating sensation in the brake pedal can also be a warning sign for an issue with ceramic brake pads. When the pads become uneven or warped, they may cause the brake system to vibrate, resulting in an uncomfortable driving experience.

Excessive Brake Dust:

Another common sign is brake dust accumulation on your wheels. It may indicate that the ceramic brake pads wear down quickly, generating excessive friction. 

Warning Light:

In some cases, the vehicle’s dashboard may illuminate a warning light related explicitly to the brake system. This light can serve as an additional indication of a problem with the ceramic brake pads that may cause a grinding noise problem.

New Ceramic Brake Pads Make Grinding Noise: Problems & Solutions

Problem 1: Worn Brake Pads

Sometimes you may break the new brake pads when installing. If your new brake pads are worn, you will experience a grinding noise and inconsistent brake performance. Immediately check for the brake pads to claim a guarantee and fix the problem.

Solution:

• Start parking the vehicle on a level surface and engage the parking brake.
• Then remove the wheel for the suspected brake pad.
• Check the brake pad through the caliper opening; look for thin material or metal-on-metal contact.
• Remove the caliper, old pads, and hardware if the pad is worn.
• Install the new ceramic brake pads. I recommend Wagner Brake QuickStop ZD1288 Ceramic Disc Brake Pad Set. It is affordable and performs excellently with multiple vehicles.
• Reinstall the wheel and take a test drive before driving on the road.

Problem 2: Misaligned Brake Pads

Proper alignment is essential for the smooth performance of the brake pads. Misaligned brake pads can cause new ceramic brake pads to make a grinding noise. It can lead to uneven contact and rubbing against the rotor surface, causing noise. You must check and fix that issue to enjoy smooth braking.

Solution:

• Park the vehicle on a level surface.
• Then engage the parking brake.
• Remove the wheel and visually check for the brake pads.
• Look for uneven wear, rubbing marks, or signs of misalignment.
• Check the brake caliper and mounting bracket for loose or damaged components.
• If there is a misalignment, loosen the caliper mounting bolts and then adjust the brake pads’ position to align them correctly.
• Retighten the caliper mounting bolts.
• Reinstall the wheel and test the brakes to ensure the issue has been removed.

Also, check for misalignment when experiencing both front brake calipers not releasing properly.

Problem 3: Rusted Brake Rotors

Rusted brake rotors can cause new ceramic brake pads to make a grinding noise. It happens because rust buildup on the rotor surface creates an uneven surface. It may lead to friction and noise when the pads come into contact.

Solution:

• Inspect the brake rotors for rust, such as a reddish-brown coating on the rotors.
• Then try to listen to the grinding noise by rotating the wheel and applying the brakes.
• If rust is present and causing the noise, remove the brake pads.
• Take a wire brush and scrub away rust from the rotors’ surface.
• Clean the rotors with brake cleaner spray. You have many choices, but I recommend CRC Brakleen 05050 Brake Parts Cleaner.
• Install new ceramic brake pads.
• Test the brakes to ensure the noise issue is resolved.

Problem 4: Damaged Brake Caliper

Brake calipers are responsible for the proper working of the system. If you have damaged the brake caliper, it may cause brake system issues. You should check for the calipers and ensure no wear or damage.

Solution:

• Remove the wheel, exposing the brake assembly.
• Then check for the caliper for damages, such as leaks, cracks, or misalignment.
• If damage is detected, replace the damaged caliper with a new one. I recommend the Power Stop Rear S2792A Pair of High-Temp Red Powder Coated for replacement.
• Lubricate the caliper slides and mounting bolts before installing the new caliper.
• Reassemble the brake assembly and secure the wheel.
• Test the brakes for proper functionality and ensure the grinding noise has ceased.

Damaged brake calipers can cause Ford integrated trailer brake controller problems. Learn how you can troubleshoot such issues. 

Problem 5: Insufficient lubrication

Insufficient lubrication is a common cause for new ceramic brake pads to make a grinding noise. The pads can not move smoothly within the caliper brackets without proper lubrication, leading to friction and noise during braking.

Solution:

• Lift the vehicle safely and remove the wheels.
• Then check the brake pads for poor lubrication.
• Clean the caliper slides and pins using a suitable brake cleaner.
• Apply a thin layer of high-temperature brake lubricant on the caliper slides and pins.
• Reinstall the brake pads, ensuring proper alignment.
• Then reinstall the wheels and lower the vehicle.
• Test the brakes to ensure the grinding noise is resolved.

Risks Of Ignoring Grinding Noise in Ceramic Brake Pads 

Safety Hazard: 

Ignoring grinding noise in ceramic brake pads can be a significant safety risk. The noise usually indicates that the brake pads are worn down to their metal backing plates. It can lead to reduced braking efficiency and increased stopping distances. It can be dangerous, especially on rushy roads.

Increased Repair Costs: 

You may experience severe damage to the braking system. Continued use of worn brake pads can result in rotor damage, requiring expensive repairs or even replacement. 

Reduced Performance:

Grinding noise often signifies excessive wear or damage to the brake pads. As a result, the braking performance can be compromised. It may lead to longer stopping distances, decreased control, and increased risk of accidents.

Potential for Rotor Damage: 

The metal braking plates of the brake pads can directly contact the rotors if you ignore the grinding noise. It may cause scoring, grooving, or warping of the rotors. It will require costly repairs or replacements.

Tips for Maintaining Ceramic Brake Pads

• Avoid aggressive braking; always apply gentle, gradual braking because it reduces stress on ceramic brake pads.
• Keep brake pads clean regularly and remove dust, debris, and brake fluid residue using a soft brush or compressed air.
• Regularly check for wear, cracks, or uneven surfaces. Replace pads if necessary.
• Always avoid overheating, and allow brakes to cool down after intense use to prevent pad glazing.
• Never compromise on quality; always use quality rotors. Match ceramic pads with high-quality rotors for better performance and longevity.
• Be mindful of moisture and avoid prolonged exposure to water or moisture to prevent corrosion.
