The specific steps for exhausting the brake pump of a car are as follows:
Find the master brake cylinder: The master brake cylinder is usually located in the engine compartment, either on the left or right side. The specific location can be found in the vehicle manual.
Operation of the exhaust screw: There is a screw on the master brake cylinder that is specifically used for exhaust, usually made of metal. Use a special tool (such as a screwdriver) to unscrew this screw and exhaust the air. Repeatedly operate the screw until no bubbles are generated after several consecutive operations, thus completing the process of exhausting the brake air.
Exhaust of the slave cylinder: Remove the exhaust dust cover on the slave cylinder, prepare a transparent hose, connect one side to the exhaust valve and the other side to the plastic container. One person steps on the brake pedal several times in the car, and then presses the brake pedal hard until it stops. Another person loosens the exhaust screw on the slave cylinder outside the car, and the air will be exhausted along with the oil. Repeat the above operation until there are no bubbles in the exhausted oil.
Precautions: During the exhaust process, be careful not to loosen the screw and exhaust the air at the same time to avoid exhausting the air completely. At the same time, when stepping on the brake, you should step on the brake step by step to the bottom, and make sure not to release the brake until the person who bleeds the air sends a message.
The role of the brake pump in the automobile braking system: The brake pump is an indispensable chassis brake part of the braking system. Its main function is to push the brake pads, which rub against the brake drum to achieve the braking of the vehicle.
