Advantages and maintenance of air disc brakes
What advantages does an air disc brake have over other brakes? What do you need to do to maintain the air disc brakes? Let's take a look at the advantages and maintenance of the air disc brakes, I hope to help everyone.
Advantages of air disc brakes
Air disc brakes have many advantages over other brakes. It is less affected by the coefficient of friction, which means that the braking performance is relatively stable, even if it is submerged, its performance is reduced, and recovery is faster. The amount of thermal expansion of the brake disc in the thickness direction is extremely small. In addition, it is easy to realize the automatic adjustment of the space gap, and the operation and the subsequent maintenance are simple.
Compared with the drum brake, the working surface of the air disc brake heats the front surface of the plane. The rotation of the disc is easy to cool, and it is not easy to cause large deformation. The most important point is that its braking performance is relatively stable. Even if the brake disc expands due to high temperature after a long period of use, the braking effect is increased, which is a feature that the drum brake does not have. In addition, the structure of the air disc brake is simpler, and the maintenance is also convenient, and the automatic adjustment of the brake gap is easy.
Maintenance of air disc brakes
1. Check the wear limit thickness of the brake disc. The limit thickness of the brake disc wear is 8 mm. If the thickness is lower than this standard, new accessories must be replaced immediately for consideration of driving safety.
2. Use the dial indicator to detect the section runout error of the brake disc. The surface of the auto disc has obvious wear steps and strain grooves, which can be processed and repaired.
3. At the same time, check the thickness of the automatic friction plate. The thickness of the friction plate should not be less than 7 mm. If it is less than 7 mm, the friction plate must be replaced. Also check the brake caliper body and replace it if it is found to have oil leakage.
The above is about the advantages of air disc brakes and maintenance work. I hope everyone can understand the advantages of air disc brakes and maintenance work, it will help everyone.
