The working principle of the automobile brake pump is that by stepping on the brake pedal, the piston in the brake master cylinder is thrusted, and then the brake fluid is transmitted to each brake cylinder through the push rod and the oil pipe, pushing the brake pads and the brake drum to produce friction, thereby achieving the braking effect. Depending on the model, the brake pump can be divided into two types: air brake master cylinder and oil brake master cylinder. While the air brake master cylinder controls the flow of brake oil back to the oil tank, the vehicle's air brake is usually equipped with several large air tanks, which will directly discharge air after braking, so the exhaust sound is loud. The oil brake master cylinder achieves braking through the hydraulic system.
The brake pump is an important part of the automobile brake system, and its working process involves the synergy of multiple components. When the brake pedal is stepped on, the piston in the brake master cylinder is thrusted, and the brake fluid is transmitted to each brake cylinder through the push rod and the oil pipe. The piston inside the cylinder begins to move under the action of the hydraulic pressure, pushing the brake pads and the brake drum to rub, thereby achieving the deceleration and stop of the vehicle.
In addition, the maintenance and troubleshooting of the brake pump are also key to ensuring its normal operation. Common faults include slow return of the brake cylinder, which may be caused by piston or pipe jam, rusted brake fluid or brake pad problems. Solutions include checking and cleaning the jammed part, changing the brake fluid and cleaning the cylinder.
