What's the matter with the air brake safety valve popping up all the time?
1. If there is a squeak at the position where you step on the brake pedal when parking, most of the brake light switch return springs on the brake pedal will squeak.
2. If it is the creaking sound of the brake when the vehicle is driving at a low speed, it may be caused by the sound from the position of the brake disc. Check whether the brake pads are excessively worn or whether foreign objects enter the brake pads.
Function of air brake safety valve
Step on the brake pedal, open the valves of the master cylinder (all of them are one-way valves, which can only take air in and cannot return), and compressed air enters the front brake cylinder and the rear brake spring cylinder through the one-way valves, which pushes the brake arm, rotates the brake cam, unfolds the brake shoes (mostly copper asbestos brake pads) and closely contacts the brake drum (cast iron) to achieve the purpose of braking.
At present, the pipeline system with double circuits and cross braking is adopted to ensure that the pipeline has local leakage and braking.
