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.
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.
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.
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.
