How to adjust the pneumatic brake?

When the vehicle is running normally, with the increase of braking times, the clearance wear between the brake shoe and the brake hub will become larger or abnormal, thus reducing the braking efficiency. At this time, it must be adjusted, otherwise it will lead to traffic accidents. In fact, the adjustment is also very simple, and it can be carried out without disassembling parts and thickness gauge.

The method includes the following steps: after the vehicle stops at the straight-line driving position, firstly, screw the adjusting screw of the brake arm to the bottom, so that the gap between the brake hub and the brake shoe is zero; Then loosen the adjusting screw in the opposite direction for about one turn to get the normal clearance (0.2-0.6 mm). Adjust the adjustment screws of the other three brake arms in the same way, and then test the braking effect at medium speed. If the braking effect meets the requirements, the adjustment is completed. If the braking force is inconsistent, a screw can be properly adjusted according to the brake wheel print until it meets the requirements.
