1. Abnormal noise when braking

当刹车时，刹车系统会发出金属摩擦的尖锐刺耳声。

When braking, the brake system will make a sharp screeching sound of metal friction.

这个可能是由于刹车片变薄，刹车片凹陷，刹车片有异物或刹车盘生锈等原因引起的，一般情况下多踩几次刹车异响都会有缓解。

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.刹车片偏移

2. Brake pad offset

刹车偏现象并不十分普遍，主要表现在踩刹车时方向盘有明显的侧倾。

The phenomenon of brake deflection is not very common, mainly manifested in the obvious roll of the steering wheel when the brake is applied.

其原因可能是刹车片磨损过大，制动分泵出现故障等。

The reason may be that the brake pads are worn too much and the brake cylinder fails.

3.制动硬化

3. Brake hardening

许多卡友都会遇到刹车失灵的问题，造成刹车失灵的原因主要有真空助力器故障，导致制动失灵，频繁踩下刹车后导致刹车制动失灵等。

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.踩刹车时反弹

4. Rebound when stepping on the brake

很多卡友都遇到过这样的情况，在踩刹车的时候，刹车踏板有反弹顶脚的现象，这种现象主要是刹车盘、刹车片表面不平整，钢圈变形等造成的。

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.

总之，刹车系统存在很多问题，当出现问题时，不要讳疾忌医，更好能做到自己先简单地查一查确认问题严不严重，能不能继续开到修理厂，绝不能忽

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

视刹车，因为这关系到大家的平安。

It depends on the safety of the brake, because it is related to everyone's safety.
