What does the partial brake mean? How to adjust the truck partial brake?

Braking system is a very important system in automobile, which is related to driving safety factor.

If the wheels on the upper and lower sides of the truck are different, it will also affect the eccentric braking phenomenon.

The meaning of partial braking is that the left and right brakes are unbalanced, and the emergency braking is easy to deviate, so it is impossible to brake at the same time.

If the old and new degree of the wheels on the upper and lower sides is different, the grip of the tire is different, and there will be partial braking when braking.

The tire of the car is the only part in contact with the ground. When braking, if the tire has good grip, the car can stop quickly.

If the grip of the tire is not good, the braking distance of the car will be extended, and there may even be locking.

Therefore, when there is partial braking, not only the braking system, but also the tires should be tested.

There are three main reasons for truck brake deviation:

1、 Braking force of left and right wheels;

2、 Response time;

3、 Motion interference;

For the gap discrepancy fed back usually, it is only a small aspect that affects the brake deviation, but also depends on the contact area, friction coefficient, etc;

Treatment method of truck eccentric brake:

The first step is to adjust the tire, rim and brake drum from left to right. If the brake deviation direction changes, for example, from right deviation to left deviation, it is a brake drum problem and needs to be replaced; If the problem is eliminated, the cause is unknown;

The second step is to replace the left and right shoe assemblies. If the brake deviation direction changes, it is a brake problem and the brake needs to be replaced. If the problem is eliminated, the reason is unknown. https://www.chinaaxle.cn
