Common faults of car brake pads?
[Catalog:News] [Date:2024/1/10] [Hits:] [Return]
Common faults of automotive brake pads include the following:
1. Brake does not return:
When the brake pedal is pressed, the pedal cannot return quickly or slowly. This situation is usually caused by dirt on the piston of the slave pump. The solution is to treat the piston of the brake cylinder and ensure that the air inside the brake pipeline and brake oil is completely drained.
2. Brake becomes soft:
The phenomenon of brake softening is quite common, which may be due to insufficient brake oil, excessive wear of brake discs and pads, or air in the brake pipes. Deterioration and lack of brake fluid are the most common reasons.
3. Abnormal noise during braking:
Brake noise is usually caused by thinning of brake pads, poor quality of brake pads, foreign objects in brake pads, or rusting of brake discs. After applying the brakes a few times, the abnormal noise may be reduced.
4. Brake failure:
Brake failure is a very serious problem that usually does not occur. When a car experiences quality issues or brake system malfunctions, the likelihood of brake failure increases. If the brake fails, the first step is to control the vehicle speed, gradually downshift, and use the engine brake to reduce the speed. When the speed is below 60 kilometers per hour, consider using the handbrake to slow down, as excessive speed increases the risk of accidents.
5. Spring feet:
There are two situations when bouncing the foot. One is the feeling of the pedal bouncing when pressing the brake hard, which is a normal phenomenon; Another type is abnormal wear of brake discs, such as uneven lines appearing on the brake discs. This situation will cause bouncing and a decrease in braking force. The solution is to replace the brake discs and pads as soon as possible.
6. Brake hardening:
Brake hardening is usually caused by the failure of the vacuum brake pump. The vacuum brake pump has two chambers, one connected to the intake manifold and the other connected to the external atmosphere. When the engine is working, the intake manifold takes in air, creating negative pressure. When braking is required, the difference in air pressure between the two is used to generate assistance. By applying pressure to the brake fluid, the brake pads and discs rub against each other, thereby generating braking force.
7. Brake deviation:
When braking, the steering wheel deviates and the vehicle body deviates from the straight track. This type of malfunction is caused by an imbalance in the left and right braking forces
