1. Abnormal noise when braking
When braking, the brake system will make a sharp screeching sound of metal friction.
This may be caused by thin brake pads, sunken brake pads, foreign bodies in brake pads or rust on brake discs. In general, the abnormal noise will be alleviated by stepping on the brake several times more.
2. Brake pad offset
The phenomenon of brake deflection is not very common, mainly manifested in the obvious roll of the steering wheel when the brake is applied.
The reason may be that the brake pads are worn too much and the brake cylinder fails.
3. Brake hardening
Many card friends will encounter the problem of brake failure. The main causes of brake failure are the failure of vacuum booster, which leads to brake failure, and frequent application of the brake results in brake failure.
4. Rebound when stepping on the brake
Many kayou have encountered this situation. When stepping on the brake, the brake pedal rebounds against the top foot. This phenomenon is mainly caused by the uneven surface of the brake disc and brake pad, and the deformation of the steel ring.
In a word, there are many problems in the brake system. When there are problems, don't be afraid to avoid doctors. It's better to simply check whether the problem is serious or not, and whether you can continue to drive to the repair shop
It depends on the safety of the brake, because it is related to everyone's safety.
