In addition to traffic safety, we need to pay attention to traffic safety in the process of driving. One of the major objective reasons for traffic accidents is the breakdown of the car's braking system. However, this reason is objective but not unforeseeable and preventable. Today Xiao Bian took everyone to understand the cause of the breakdown of the brake system. From the source, we can avoid danger and ensure safety.
Failure Analysis: What is the cause of frictional slippage?
1, the friction block material deterioration. For example, when the vehicle is used for braking for a long time or frequently, the friction block and the brake disc are frictionally rubbed to generate high temperature, and the organic polymer in the material decomposes at a high temperature.

2, brake discs are generally made of steel, although there is a certain degree of metal hardness, but the high temperature will not be oxidized, not only the hardness is reduced, but also will be too fast cooling deformation, resulting in rapid wear of the brake disc, disk surface roughness, and Deep grooves are created. Even if the new friction plate is replaced, the brake will not be improved. In addition, if the deformation is severe, the wheel will be unbalanced and the body will shake.
3. When brakes are used under friction and slipping conditions, the temperature will become higher and higher, which will inevitably lead to an increase in the temperature of the brake cylinder and aging of the rubber parts. These are all adverse factors that affect braking.
Therefore, in addition to the routine inspection of the hydraulic braking system of the vehicle, special attention should be paid to the surface roughness of the friction material, which is very important to ensure the braking effect.
Xiao Bian reminds everyone here that you must not neglect the automobile research and safety inspections. In particular, the daily attention of the braking system is very likely to save your life in dangerous times!
