How Often Should the Brake Pump Be Replaced?

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.
I've been working with vehicle braking systems, and there's no fixed interval for replacing the brake master cylinder - it entirely depends on usage and individual driving habits. If you frequently drive in urban traffic congestion or on steep mountain roads where brakes are used intensively, this can accelerate cylinder wear. Typically, I recommend inspecting the entire braking system every two years, including checking the brake fluid and cylinder condition. If you notice symptoms like a soft brake pedal, delayed response, or signs of fluid leakage, these indicate the cylinder needs replacement. Additionally, brake fluid changes are crucial - I replace mine every two years because it absorbs moisture which degrades performance and shortens cylinder life. Never wait until an emergency situation arises; brake failure could be catastrophic. Regular maintenance prevents major issues and extends your vehicle's lifespan.
