Next, let's briefly talk about the methods of handling the abnormal braking of the concrete mixer, hoping to bring you useful information.

1，刹车时异响

1. Abnormal noise when braking

踩刹车时，刹车系统会发出尖锐刺耳的金属摩擦声。

When you step on the brake, the brake system will make a sharp metal friction sound.

这有可能是因为刹车片变薄、刹车片坑洼、刹车片中有异物或刹车盘生锈等导致，一般情况多踩几脚刹车异响都会有缓解。

This may be caused by thin brake pads, pitted brake pads, foreign matters in the brake pads, or rust on the brake disc. Generally, the abnormal noise can be alleviated by stepping on more brakes.

2，刹车踏板行程变长

2. Brake pedal travel becomes longer

刹车行程变长的原因主要是刹车系统中进入空气、缺少刹车油、可能存在泄漏、刹车片磨损严重等。

The main reasons for the longer brake stroke are air entering the brake system, lack of brake oil, possible leakage, and severe wear of brake pads.

3，刹车跑偏

3. Brake deviation

刹车跑偏的现象不是很常见，主要体现在踩刹车时方向盘有明显的向一侧偏转。

The phenomenon of brake deviation is not very common, which is mainly reflected in the obvious deflection of the steering wheel to one side when stepping on the brake.

4，刹车变硬

4. The brake becomes hard

很多卡友会碰到刹车变硬的问题，刹车变硬的原因主要有真空助力器故障导致刹车无助力、频繁踩刹车后导致等造成。

Many card users will encounter the problem of brake hardening. The brake hardening is mainly caused by the failure of the vacuum booster, which causes the brake to have no power, and frequent brake application.

踩刹车时反有不少卡友碰到过这种情况，在踩下刹车时刹车踏板有反弹顶脚的现象，这种现象多为刹车盘、刹车片表面不平、钢圈变形等导致。

Many customers have encountered this kind of situation when stepping on the brake. When stepping on the brake, the brake pedal rebounds. This phenomenon is mainly caused by the uneven surface of the brake disc and brake pad and the deformation of the steel rim.
