The importance of the brake system of the automatic mixer truck, the vibration when stepping on the brake mostly occurs on the old truck. Due to wear, the surface finish of the brake disc of the mixer truck is not aligned to a certain extent. Therefore, it is recommended to use the lathe disc technology to grind or replace the brake pad (used for the old concrete mixer) according to the situation.
When the braking device of the truck 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 mixer brake disc, the difference between the uneven action of the pump and the rapid friction is very small, so it is difficult to feel it.
It takes more than ten minutes for the hot car to start the small mixer. In the brake system of the all-in-one truck, the engine provides pressure to push the calipers 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, it may be that there is no pressure in the oil pipeline providing the pressure, resulting in the failure to provide the braking force in time. In this case, the vacuum power hose of the main brake pump and the engine of the small concrete mixer should be checked for cracking or loosening.
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 are leaking, and whether the main pump and pump components are damaged.
