Disc brake pads are an important component of the automotive braking system, playing a crucial braking role. However, sometimes the braking system may malfunction, posing potential risks to driving safety. This article will provide a detailed introduction to common faults of disc brake pads and provide some simple and practical troubleshooting methods to help you easily solve brake failure problems.

1、 Uneven wear of brake pads
Uneven wear of brake pads may lead to brake failure, brake shaking, and other issues. The troubleshooting method is as follows:
Check the thickness of the brake pads: Measure the thickness of the brake pads to ensure that it is not below the minimum thickness recommended by the manufacturer. If it is below the minimum thickness, the brake pads need to be replaced.
Check the installation of the brake pads: Ensure that the brake pads are correctly installed on the brake calipers without any looseness or misalignment. If there are any problems, adjust or replace them in a timely manner.
Grinding or replacing brake pads: If the brake pads wear unevenly and do not reach the minimum thickness, grinding can be attempted to make their surface flat. If the wear is too severe, it is necessary to replace the brake pads in a timely manner.
2、 Brake system noise issue
Brake system noise may be caused by various factors, such as vibration between brake pads and brake discs or foreign objects entering the brake system. The troubleshooting method is as follows:
Clean brake discs and pads: Use brake cleaner to thoroughly clean the brake discs and pads to remove any dirt or deposits that may cause noise.
Check the installation of the brake pads: Ensure that the brake pads are correctly installed and fully in contact with the brake caliper, without any looseness or misalignment. Adjust the position of the brake pads to ensure good contact.
Check brake system components: Check other components in the brake system, such as brake calipers, brake discs, brake covers, etc., to ensure they are not damaged or loose.
Using anti noise coatings or accessories: Applying a layer of anti noise coating to the back of the brake pads or brake calipers, or installing noise damping accessories, can effectively reduce brake system noise.
3、 Brake failure or insufficient braking force
Brake failure or insufficient braking force is a serious brake failure that requires immediate resolution. The troubleshooting method is as follows:
Check brake fluid: Ensure that the brake fluid is sufficient and there are no leaks. If the brake fluid is insufficient or leaking, it is necessary to repair the brake fluid system and replenish or replace the brake fluid.
Check the brake system: Check components such as the brake master cylinder, brake pipes, and brake calipers to ensure they are not damaged or blocked. Repair or replace as necessary.
Degassing brake system: If there are bubbles in the brake system, it will affect the braking force. The air bubbles are expelled from the brake system through the degassing process, restoring normal braking effect.
4、 Other common troubleshooting methods
Overheating of brake pads: Overheating of brake pads may lead to brake failure or reduced braking force. Avoid continuous high-speed braking and reduce the speed appropriately to reduce the accumulation of heat in the brake pads.
Brake pad jamming: Brake pad jamming may be caused by brake caliper jamming or dirty brake system. Check the brake calipers and brake system, clean and repair them.
The failure of disc brake pads may lead to serious braking problems and threaten driving safety. By checking the wear of brake pads, cleaning the brake system, adjusting the installation of brake pads, and maintaining the brake hydraulic system, braking faults can be effectively eliminated. However, for complex brake failures, it is recommended to seek the help of professional technical personnel to ensure the normal operation of the brake system and driving safety.
