How Often Should the Brake Pump Be Replaced?

[LolaFitz]

The brake wheel cylinder does not have a fixed replacement interval. As long as the brake wheel cylinder is not damaged, it does not need to be replaced. Below is relevant information: Function of the brake pump: The brake pump is the main control device in the vehicle's service brake system, achieving sensitive follow-up control during the braking and release processes of the dual-circuit main braking system. Working principle: When the driver steps on the pedal, the pull rod is stretched, causing one end of the pull arm to press down on the balance spring, which in turn moves the balance arm downward. This first closes the exhaust valve and opens the intake valve. At this point, compressed air from the air reservoir enters the brake chamber through the intake valve, pushing the chamber diaphragm to rotate the brake cam, thereby achieving wheel braking and the desired braking effect.
