Self loading concrete mixing tank truck is a special heavy truck. When mixing fuel tank, it has large payload, complex road conditions and large inertial centrifugal force, which puts forward high requirements for the braking system of mixer. Although the braking system is very important for the mixer system, the first consideration in determining the safety of the mixer is the braking distance of the car and the thermal degradation of the brake.

如果卡车的制动系统出现问题，驾驶员和乘客也将面临危险。因此，在驾驶或踩刹车时，需要注意刹车。

If there is a problem with the truck's braking system, the driver and passengers will also be at risk. Therefore, when driving or stepping on the brake, you need to pay attention to the brake.

1.制动时发出异常声音

1. Abnormal sound during braking

踩刹车时，刹车系统会产生剧烈的金属摩擦。

When you step on the brake, the brake system will produce severe metal friction.

这可能是由于刹车片中的异物，刹车盘上的锈蚀等引起的。

This may be caused by foreign matters in the brake pad and corrosion on the brake disc.

2.刹车踏板行程变长

2. The brake pedal travel becomes longer

刹车松开时，您会看到一个直的白点。

When the brake is released, you will see a straight white dot.

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，可能的泄漏以及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

制动偏差不是很常见，主要反映了在施加制动时方向盘偏向一侧的事实。

Braking deviation is not very common, which mainly reflects the fact that the steering wheel is biased to one side when braking is applied.

这种现象的原因可能是制动衬块的偏心磨损和制动缸的问题。

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

4.刹车越来越难

4. Braking is becoming more and more difficult

许多卡都有增加刹车的问题。加强制动器的主要原因是真空助力器的故障。没有辅助制动，经常使用制动。

Many cards have the problem of adding brakes. The main reason for strengthening the brake is the failure of the vacuum booster. There is no auxiliary braking, and the braking is often used.

5.刹车的反弹

5. Rebound of brake

许多卡伙伴都遇到了这种情况，但是在应用制动器时，会出现上肢弹回制动踏板的现象，这主要是由于制动盘表面不平整所致。垫片和钢圈变形

Many card partners encounter this situation, but when the brake is applied, the upper limb will bounce back to the brake pedal, which is mainly due to the uneven surface of the brake disc. Deformation of gasket and steel ring
