The coefficient of friction is the most important performance index for uating all friction materials. The ability to brake to the brakes. During the braking process, heat is generated by friction, The working temperature of the friction member is increased, and the friction material of the general brake pad is affected by the temperature.
The friction coefficient begins to decrease, which reduces the friction and reduces the braking effect. general Brake material friction material selection is not suitable, friction coefficient is too high, resulting in braking process The direction is out of control, and when the temperature is too high, the burning phenomenon will occur, and the braking effect will be produced.
If it is worse, it may also scratch the brake disc. High quality brake pads even if brakes When the disk temperature is as high as 650 °C, the friction coefficient of the brake pad is still 0.45~0.55. Can guarantee the vehicle has good braking performance, and at the same time overcome the ordinary brake pads Disadvantages.
