Self feeding concrete mixer is a special heavy truck. When mixing fuel tank, it has large load capacity, complex road condition and large inertial centrifugal force, which puts forward high requirements for the braking system of mixer. The braking system is very important for the mixer system, but when determining the safety of the mixer, the first consideration is the braking distance of the lift car and the thermal degradation of the brake.

如果卡车的制动系统出现问题，驾驶员和乘客也有危险。因此，在驾驶或踩刹车时，请务必小心。

If there is a problem with the truck's braking system, the driver and passengers are also at risk. Therefore, be careful when driving or braking.

1.制动时发出异常声音

1. Abnormal sound during braking

踩刹车时，刹车系统会引起强烈的金属摩擦。

When stepping on the brake, the brake system will cause strong metal friction.

原因可能是刹车片上的异物或刹车盘生锈。

The reason may be foreign matters on the brake pad or rust on the brake disc.

2.制动踏板的行程变长

2. The travel of the brake pedal becomes longer

随着刹车的软化，您会看到笔直的白点。

As the brakes soften, you will see straight white spots.

较长的制动行程的原因主要是由于空气进入制动系统，缺少制动油，可能的泄漏和制动衬块的严重磨损。

The long braking stroke is mainly due to the air entering the braking system, lack of brake oil, possible leakage and serious wear of brake pads.

3.制动偏差

3. Braking deviation

刹车打滑不是很常见。这主要反映了这样一个事实，即在施加制动时，方向盘会向一侧弯曲。

Brake slip is not very common. This mainly reflects the fact that when braking is applied, the steering wheel will bend to one side.

造成这种现象的原因可能是制动衬块偏心磨损和制动缸问题。

This phenomenon may be caused by eccentric wear of brake pads and brake cylinder problems.

4.制动困难

4. Difficult braking

许多卡都有增加制动的问题。加强制动器的主要原因是真空助力器的故障。刹车不辅助，经常使用刹车。

Many cards have the problem of increasing braking. The main reason for strengthening the brake is the failure of the vacuum booster. The brake is not assisted, and the brake is often used.

5.刹车回弹

5. Brake rebound

许多伙伴都遇到了这种情况，但是当他们踩刹车时，上肢会从刹车踏板上弹起，这主要是由于刹车盘表面不平整所致。垫片和钢圈变形。

Many partners encounter this situation, but when they step on the brake, their upper limbs will bounce off the brake pedal, which is mainly due to the uneven surface of the brake disc. The gasket and steel ring are deformed.

自进料混凝土搅拌车的异常运行，一定要多注意，一旦发现应立即前往维修点！
