Automobile brake pump: What is, principle, composition and maintenance
The automobile brake sub-pump is an important part of the automobile brake system, which mainly transmits the liquid pressure generated by the brake master pump to the brake pads, so that the friction between the brake pads and the brake disc is generated, and the purpose of brake deceleration is finally realized. The brake sub-pump can be divided into front brake sub-pump and rear brake sub-pump according to the different installation position. The front brake pump is usually installed on the front wheel of the car, and the rear brake pump is usually installed on the rear wheel of the car.

Working principle of brake pump
The working principle of the brake sub-pump is that when the driver presses the brake pedal, the brake master pump will transport the brake fluid to the brake sub-pump, and the piston of the brake sub-pump will push the brake pad to contact the brake disc under the push of the brake fluid, thus generating friction and slowing down the car. When the driver releases the brake pedal, the brake master pump will stop conveying brake fluid, the piston of the brake branch pump will be reset under the action of the reset spring, the brake pad and the brake disc are separated, and the car stops slowing down.

Brake sub-pump composition
Brake pump is mainly composed of piston, piston rod, seal ring, brake fluid, reset spring and so on. Among them, the piston is the main actuator of the brake pump, which mainly plays the role of transferring the pressure of the brake fluid to the brake pads; The piston rod is an extension of the piston, which mainly plays the role of connecting the brake pedal and the piston; The sealing ring mainly plays the role of sealing brake fluid and preventing leakage; Brake fluid is the working medium in brake system, which mainly plays the role of transferring brake pressure. The reset spring is mainly used to reset the piston after the driver releases the brake pedal.

Maintenance of brake pump
Brake pump is an important part of the automobile brake system, and its maintenance is very important to ensure the normal work of the brake system. The maintenance of brake pump mainly includes the following aspects:
Regularly check the appearance of the brake pump, whether there are cracks, deformation and other defects;
Check the brake fluid level of the brake pump regularly to see if it is lower than the lowest level line;
Replace the brake fluid of the brake pump regularly, generally every two years or 40,000 kilometers;
Regularly check whether the piston of the brake pump is stuck and whether it can be reset normally;
Regularly check whether the seal ring of the brake pump is aging and damaged, and replace it in time if it is damaged;
