Common problems and solutions in the use of disc brake pads
Disc brake pads are a core component of automotive braking systems, but they may encounter some common problems during use.
Part 1: Common Questions
Brake failure or insufficient braking force: When the brake pedal is pressed, the brake loses response or the braking force is insufficient, which may be caused by the following reasons: brake fluid leakage, brake system bubbles, severe wear of brake discs or pads, etc.
Brake noise: Creak, squeak, or sharp piercing sound generated during braking, which may be caused by friction between the brake pads and brake discs.
Brake vibration: Feeling the steering wheel or vehicle itself shaking when braking, which may be caused by imbalanced brake discs, uneven wear of brake discs, or brake caliper issues.
Brake pad wear too fast: The brake pad wear rate is abnormally fast, which may be caused by poor brake pad quality, improper braking habits, or brake system failure.
Part 2: Solutions
Here are some solutions to the common problems mentioned above:
1. Brake failure or insufficient braking force:
Check for brake fluid leaks and promptly repair any leaks to ensure the sealing of the brake system.
Exhaust brake system to remove air bubbles and ensure that there is no air inside the brake system.
Check the wear level of the brake discs and pads, and if necessary, replace severely worn components in a timely manner.
2. Brake noise:
Clean the surface of the brake pads and brake discs to remove accumulated dust and dirt.
Check the flatness of the brake pads and brake discs. If there are dents or imbalances, replace damaged components in a timely manner.
Use appropriate brake pads and choose materials with better noise reduction performance.
Apply appropriate lubricant between the brake pads and brake calipers to reduce friction and noise.
3. Brake judder:
Check if the brake disc is flat. If there are dents, uneven wear, or deformation, the brake disc needs to be replaced.
Check if the brake calipers are working properly to ensure smooth piston movement. If any problems are found, repair or replace the brake calipers.
Ensure that the brake disc and wheel bolts are tightened, as loose bolts may cause brake shaking.
4. Brake pads wear too quickly:
Check the fit of the brake pads and brake discs to ensure even contact between them.
Pay attention to reasonable driving habits, avoid sudden braking and prolonged pressing of the brake pedal, and reduce brake pad wear.
Select high-quality brake pads and regularly replace them according to the manufacturer's recommended replacement cycle.
Common problems in the use of disc brake pads, such as brake failure, brake noise, brake shaking, and rapid wear, can have a negative impact on driving safety and brake performance. Timely detection and resolution of these issues is crucial. By inspecting and maintaining various components of the brake system, ensuring the normal operation of the brake discs, pads, and calipers, and following reasonable driving habits, braking problems can be effectively reduced. However, for complex or serious braking problems, it is recommended to seek the help of professional technicians to ensure the safety performance of the braking system.
