What is the front brake pump
Brake pump is an indispensable chassis brake part of the brake system, its main function is to push the brake pad, the brake pad friction brake drum. Slow down and stop. After the brake is pressed, the main pump generates thrust to press the hydraulic oil to the sub-pump, and the piston inside the sub-pump begins to move under the liquid pressure to push the brake pad.
Hydraulic brake is composed of brake master pump and brake oil storage tank. They're connected to the brake pedal at one end and the brake tubing at the other. Brake oil is stored in the brake master pump, and an oil outlet and an oil inlet are provided.
The air brake is composed of an air compressor (commonly known as an air pump), at least two air storage cylinders, a brake master pump, a quick release valve of the front wheel, and a relay valve of the rear wheel. The brake consists of four pumps, four dispensing backs, four cams, eight brake shoes and four brake hubs.
Hydraulic brake
The oil brake is composed of a brake master pump (hydraulic brake pump) and a brake oil storage tank.
Heavy trucks use air brakes, and general cars are oil brakes, so the total brake pump and brake pump are hydraulic brake pumps. Brake pump (hydraulic brake pump) is an indispensable part of the brake system. When you step on the brake plate, the brake master pump will send the brake oil through the pipeline to the brake pump. The brake subpump has a connecting rod that controls the brake shoe or brake skin. When braking, the brake oil in the brake tubing pushes the connecting rod on the brake pump, so that the brake shoe tights the flange disc on the wheel to stop the wheel. The technical requirements of a car's brake pump are very high, because he directly affects people's lives.
Do not change the brake oil for a long time, resulting in rust inside the brake pump, the brake pump and the hanging screw outside, and then apply butter, and finally load the car, sand it with fine sandpaper.
Emergency treatment, the broken branch pump oil pipe is removed, and the oil pipe head is tied tightly after removal, so that all can not discharge oil or gas to the place (pneumatic brake type vehicles).
The brake pump emits an abnormal sound, which may be that the guide pin of the pump is loose, or rust and oxidation occur, as long as a new one is replaced. If there is oil leakage, it means that the brake pump has been seriously damaged, and the entire brake pump needs to be replaced.
If the brake pump is bad, the first is that the brake pads will appear abnormal wear. The second is that the brake travel becomes longer and the brake is not good. Can rise to step on the brake to see whether the brake pump return can be, as long as the return can brake pump is not easy to break.
