The importance of the braking system of the fully automatic self feeding mixer truck. Most of the vibration when the self feeding mixer truck steps on the brake occurs on the old truck. Due to wear, the surface finish of the brake disc of the concrete mixer is not aligned to a certain extent. Therefore, it is recommended to use the lathe optical disc technology for grinding or replace the brake pad (for the old concrete mixer) according to the situation.

当自上料搅拌车的制动装置即将停止时，方向盘总是偏转到一侧。事实上，这种情况通常被称为"偏置制动"。造成故障的主要原因是小型混凝土搅拌机制动系统的左右泵之间的力不均匀。在驱动过程中，由于小型混凝土搅拌机制动盘的快速转动速度，泵的不均匀作用与快速摩擦之间的差别很小，我们很难感觉到它。

When the braking device of the self loading mixer is about to stop, the steering wheel always deflects to one side. In fact, this situation is often referred to as "offset braking". The main cause of the failure is the uneven force between the left and right pumps of the braking system of the small concrete mixer. In the driving process, due to the rapid rotation speed of the brake disc of the small concrete mixer, the difference between the uneven action of the pump and the rapid friction is very small, so it is difficult for us to feel it.

热车需要十多分钟才能启动小型混合器。自动上料搅拌车的制动系统由发动机提供压力推动卡钳以夹紧制动盘(盘式制动器)，或将制动盘推到与制动鼓(鼓式制动器)的摩擦处。因此，就像在上述情况下，可能是提供压力的输油管道没有压力，导致无法及时提供制动力。在这种情况下，应检查制动主泵的真空动力皮管和小型混凝土搅拌机发动机的脱落是否开裂或松动。

It takes more than ten minutes to start the small mixer. The brake system of the automatic charging mixer is supplied with pressure by the engine to push the caliper to clamp the brake disc (disc brake) or push the brake disc to the friction with the brake drum (drum brake). Therefore, as in the above case, there may be no pressure in the oil pipeline providing pressure, resulting in the failure to provide braking force in time. In this case, check whether the vacuum power hose of the main brake pump and the engine of the small concrete mixer fall off, crack or loosen.

全自动自上料搅拌车制动不回位，踩刹车踏板，踏板不上升，无阻力，这种现象是制动器不回位，需要判断制动液是否丢失，制动泵、管路和接头是否漏油，主泵和泵部件是否损坏。

The brake of the fully automatic self feeding mixer truck does not return. When the brake pedal is pressed, the pedal does not rise and there is no resistance. This phenomenon is that the brake does not return. It is necessary to judge whether the brake fluid is lost, whether the brake pump, pipeline and connector leak oil, and whether the main pump and pump components are damaged.
