The friction pair between the disc brake disc and the disc is formed, which generates the braking torque and converts the kinetic energy of the vehicle into heat energy. During braking, the weight of the vehicle is transferred to the front axle, and the brakes of the front wheel inevitably bear the braking force.
Therefore, the front brake friction plate and brake disc are the most stressful components in the vehicle, and they are vulnerable to high temperatures, mechanical and chemical burdens. Therefore, the performance of a brake friction plate must meet three requirements: safety, comfort and service life. The criteria for evaluating the production of moving friction sheets mainly have the following factors:
Coefficient of friction - A good brake friction sheet, its coefficient of friction must be high enough, and can remain stable under various driving conditions
The dynamic friction coefficient of brake friction disc determines the braking force, and also plays a decisive role in braking balance and the stability of vehicle control during braking. A reduction in the coefficient of friction can cause a considerable change in braking performance, perhaps resulting in a substantial increase in braking distance.
Therefore, the coefficient of friction of the brake pads must be guaranteed to remain stable under all driving conditions (speed, temperature, humidity and pressure) and throughout their service life. That is to say, a good brake friction sheet, its friction coefficient must be high enough, and can remain stable under various driving conditions.
