Friction coefficient refers to the parameter of the friction efficiency of brake pads, and it is an important factor to measure the quality of brake pads. Applying a force on a horizontal surface 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 the brake pads is the friction of the brake pads. With a higher friction coefficient, the greater the brake friction, the more sensitive the braking. The car can generate greater braking force with less pedaling force. Better braking effect. But it is not as high as possible. Too high or too low friction coefficient of brake pads will affect braking performance.
If the friction coefficient is too high, the brakes will be locked or too sensitive, and the comfort and heat resistance will be poor; if the friction coefficient is too low, the brakes will be insensitive. These are not good conditions and will be safe for driving. Pose a serious threat. The coefficient of friction of ordinary brake pads is about 0.3-0.4, and that of high-performance brake pads is 0.4-0.5. The following is the friction coefficient relationship:
EE level: 0.25-0.3, suitable for European and American cars, with relatively large brake pads and low friction coefficient;
FF level: 0.35-0.45, international standard friction coefficient;
GG level: 0.45-0.5, suitable for European models;
HH level: 0.55-0.6, dedicated to racing.
