Brake system is a very important system in automobile, which is related to driving safety.

General trucks and semi-trailers are air brakes, while family cars or SUVs are oil brakes.

The braking system of a family car consists of a real pneumatic booster pump, a master brake cylinder, a brake cylinder, a brake pad and a brake disc.

After opening the engine cover, you can see a black metal disc under the windshield on the driver's side, which is a real pneumatic pump. After the driver steps on the brake pedal, this pump can provide power to help the driver step on the brake pedal together.

The front of the booster pump is the brake master cylinder. There is also an oil pot on this pump. This oil pot is used to hold brake oil.

Brake oil needs to be changed regularly, because brake oil is a liquid that absorbs water easily. After the brake oil absorbs water, the braking force will decrease and the braking distance will be extended.

When the water content of brake oil reaches 3%, riders should replace the brake oil immediately.

In the usual maintenance, riders can ask technicians to test the moisture content of brake oil with professional equipment.

During normal maintenance, you can check the remaining thickness of brake pads and the status of brake discs.

How to release the dead brake lock?

If the auxiliary cylinder cup is damaged, disconnect the connector, block the nozzle with 1 cent coins or copper skin, and then tighten the connector. After the pump is started, the lock of the air stop brake can be released.

Air braking is mostly used in the hand braking system of medium and large cars. The hand brake system of this kind of car is usually in a constant braking state with strong springs. When the car is about to run, it is an inflatable action for the driver to release the brake. Only after reaching a certain air pressure can the spring be pushed away, that is, the handbrake can be released before running. Conventional braking is to lock the transmission shaft by hand, and when braking, compressed air enters the brake air chamber to lock the wheel. When the hand brake or transmission shaft fails mechanically, the hand brake fails; When any part of the air pump, pipeline, air storage tank and brake valve fails, the foot brake will fail. Air braking can effectively avoid these dangers.

Ordinary air brake system consists of brake control mechanism, double-ring brake mechanism, central disc brake mechanism, brake, air compressor and so on. Brake operating mechanism includes brake pedal, pedal hanger, etc. The double-loop braking mechanism includes an air storage tank, a brake valve, a low-pressure alarm, an air pressure regulator, a brake pipe, a reversing valve, a relay valve, a safety valve and a drain valve. The central disc brake mechanism comprises a parking brake operating handle, a brake cable and a central disc brake.
