How to adjust the air brake?
2. Then release the three buttons in the right direction, and you will feel it when you release them.
3. If the braking effect is still not good, you'd better maintain it and change the brake pad. Braking is important.
Pneumatic braking is one of the braking methods. A series of special devices used to make the outside world (mainly the road surface) exert a certain force on some parts of the car (mainly the wheels), so as to brake them to a certain extent are collectively called braking systems.
Automobile braking system can be divided into common braking (pneumatic braking), parking braking, emergency braking and auxiliary braking according to the functions of braking system. Parking brake can be divided into central disc brake and energy storage spring brake, which is commonly called "air brake".
Extended data
The hand braking system of medium and large cars mostly adopts air braking. The hand brake system of this kind of car is usually in a constant braking state with strong springs. When the vehicle is going to run, the driver's brake release is an inflatable action, and the spring can be pushed away only after reaching a certain air pressure, that is, the hand brake can be released before running.
Conventional braking is to lock the transmission shaft with a hand brake, and when the foot brake, compressed air enters the brake 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. Dead air braking can effectively avoid these dangers.
There are similarities between ordinary air braking system and air braking system, but there are also differences. The main differences are as follows:
1, parking brake is different in nature, the former is central disc brake, which is manual, and the latter is pneumatic brake with energy storage spring, which is dynamic, and its energy supply device is completely different.
2. Ordinary air brake parking brake can only be used when the car is stationary, because its braking torque acts on the transmission shaft. If it is used when the car is running, it is easy to cause serious overload of the transmission shaft and rear axle, and the left and right wheels may rotate in the opposite direction because of the locking of the differential housing, which may lead to the car running off or even turning around when braking.
However, this is not the case with energy storage spring braking. On the contrary, because the parking braking stroke of the energy storage spring is greater than the driving braking stroke, the energy storage spring can also be used for emergency braking when the driving braking force is insufficient. Therefore, energy storage spring braking can be used not only for parking braking, but also for emergency braking. Therefore, compared with ordinary air braking, air braking system is superior in braking stability and safety.
