Brake pad failure and reason analysis

The ceramic brake pads of the car play a very important role in ensuring the safety of the driver. When the brake system fails, if the correct judgment can be made on the brake system of the car, many dangers can be avoided. With the development of the national economy, the car has entered the ordinary family, and more attention should be paid to the judgment and analysis of the fault of the brake system.


We discuss the types and causes of brake system failures in the following aspects:


First, the braking effect is not good. The car is braking normally, but the braking distance is beyond the specified value. The reasons are: (a) infiltration of air into the brake fluid; (b) There is leakage in the braking system and the system pressure cannot be guaranteed;


Second, the brake suddenly fails. Continuous braking occurs, the brake pedal is pushed to the limit, but there is no braking. The reasons are: (a) serious oil leakage occurs in the main pump or sub-pump of the brake. (b) The piston seal of the main or sub-pump brake is broken, or there is excessive air in the brake oil line.


3. Brake jitter. The reason is that the end runout of the brake disc is abnormal, the brake clamp is deformed, and the brake pad is ground into a cone.


Four, the brake deviation. The reason is that the brake clearance is inconsistent and the braking is not synchronized.


5. The brakes squeak. The reason is that the brake disc and brake pads or brake drum, shoe wear caused by uneven.


Six, the brake does not return. In this case, check whether the brake wheel is hot first. If a single brake wheel is hot, it indicates that the brake is faulty. If all four hubs are hot, the brake master pump is faulty.
