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.

如果卡車的制動系統出現問題，駕駛員和乘客也將面臨危險。因此，在駕駛或踩剎車時，需要注意剎車。

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.制動時發出異常聲音

1. Abnormal sound during braking

踩剎車時，剎車系統會產生劇烈的金屬摩擦。

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

這可能是由于剎車片中的異物，剎車盤上的銹蝕等引起的。

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

2.剎車踏板行程變長

2. The brake pedal travel becomes longer

剎車松開時，您會看到一個直的白點。

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

較長的制動行程的原因主要是由于空氣進入制動系統，缺少制動油，可能的泄漏以及制動襯塊的嚴重磨損。

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.制動偏差

3. Braking deviation

制動偏差不是很常見，主要反映了在施加制動時方向盤偏向一側的事實。

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

這種現象的原因可能是制動襯塊的偏心磨損和制動缸的問題。

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

4.剎車越來越難

4. Braking is becoming more and more difficult

許多卡都有增加剎車的問題。加強制動器的主要原因是真空助力器的故障。沒有輔助制動，經常使用制動。

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.剎車的反彈

5. Rebound of brake

許多卡伙伴都遇到了這種情況，但是在應用制動器時，會出現上肢彈回制動踏板的現象，這主要是由于制動盤表面不平整所致。墊片和鋼圈變形

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
