What are the reasons for a brake pump failure?
1 Answers
The reasons for a brake pump failure are: 1. Dirty brake fluid causing wear on the wheel cylinder; 2. Aging and wear of the wheel cylinder rubber cup; 3. Poor sealing. The brake wheel cylinder is a chassis braking component of the braking system, whose function is to push the brake pads, allowing them to rub against the brake drum, thereby reducing the vehicle speed and bringing it to a stop. The brake master cylinder, also known as the main brake oil cylinder, functions to push brake fluid and gas to each brake wheel cylinder to actuate the pistons. The brake master cylinder is a single-acting piston-type hydraulic cylinder that converts the mechanical energy input by the pedal mechanism into hydraulic energy. Brake master cylinders are divided into single-chamber and dual-chamber types, used in single-circuit and dual-circuit hydraulic braking systems, respectively.
