What is the difference between high and low friction coefficient of brake pads?

2022-09-05

Hello everyone !The friction coefficient refers to the parameter of the friction efficiency of the brake pad, and it is an important factor to measure the quality of the brake pad. Applying a force on the horizontal plane to move an object weighing 100kg, and this force is equal to its own weight, that is to say, the friction coefficient between the object and the road surface is 1, then what is the difference between the friction coefficient of the brake pads?


The difference between the friction coefficient of brake pads is the size of the friction force of the brake pads. With a higher friction coefficient, the greater the friction force of the brakes, the more sensitive the braking will be, but it is not the higher the better. The friction coefficient of the brake pads is too high or too low. will affect braking performance.


If the coefficient of friction is too high, the comfort and heat resistance will be poor; if the coefficient of friction is too low, the brakes will be insensitive. These are not good conditions and will pose a serious threat to safety. The friction coefficient of ordinary brake pads is about 0.3-0.4.
