Problems solved by technology

In addition, the air chamber shell is processed by stamping, which puts forward higher requirements for the accuracy of the inner wall of the air chamber cavity, otherwise it is difficult to ensure the smooth movement and good sealing of the air chamber piston
At the same time, due to the presence of high-pressure brake fluid in the brake chamber, and the poor sealing effect between the connecting piece of the existing brake pump and the brake housing, the existing brake pump often leaks brake fluid, requiring frequent maintenance and replacement parts , poor reliability and high maintenance cost
