1, the friction block material deterioration; skidding disc brake brake blocks after a period of time, Chi engineer summed up what several reasons and solutions. Such as: vehicle down during prolonged or frequent use of the brake, the friction block and brake disc sliding friction causes the temperature at a high temperature material of organic polymer decomposition. 2, the brake discs are generally made of steel, although there are some metal hardness, but the high temperature oxidation will not only reduce the hardness, but also cooling too quickly deformation, resulting in rapid wear of the brake disk, the disk surface roughness was reduced, and It produces a deep trench, even if the replacement of the friction disc brake will not improve, but also result in wheel dynamic unbalance deformed serious cases, the body shake. 3, friction slipping when braking, the temperature will be higher, the temperature increase will inevitably lead to the brake cylinder, rubber aging car manufacturers with the brakes, which are unhealthy factors affecting braking. Therefore, the hydraulic brake system of the vehicle, in addition to routine inspections, should also pay particular attention to the surface roughness of the friction material, it is very important to ensure that the braking effect. When changing the brake pads? In general, given the numerical brake industry is driving 3 to 50,000 km to replace one, this based on individual driving habits and road conditions may be. Can themselves visually, from the hub gap not send a loud brakes prices, we can see that the thickness of the brake pad friction material, to be replaced when left 3mm. If you do not see, hears the sound brakes, if the brakes hear the sound of the iron mill, enchant (sheet brake is recommended that you buy, buy there is alarm, brake pads when the friction material is left in the car with 3mm , will automatically alarm, physical alarm and electronic alarm). If you are old driver seat of your pants on the line, if you want to depress the brake pedal to the brakes very deep, enchant brakes it.
