1. Good thermal stability.
This is because the brake disc has no friction boosting effect on the friction pad, and because the size of the brake friction pad is not long, the area of its working surface is only 12% to 6% of the area of the brake disc, so the heat dissipation is relatively good. good.
2. Good water stability.
Because the unit pressure of the brake pad on the disc is high, it is easy to squeeze the water out, and it is also easy to shake off after being dipped in water under the action of centrifugal force. Coupled with the wiping effect of the pad on the disc, it can be restored to normal after only one or two braking after the water is discharged. The drum brake requires more than ten braking times to restore normal braking performance.
3. Good braking stability.
The braking torque of the disc brake has a linear relationship with the piston thrust of the brake cylinder and the friction coefficient. In addition, there is no self-increasing effect. Therefore, the braking torque increases more slowly during the braking process. Compared with drum brakes, It can ensure high braking stability.
4. The braking torque has nothing to do with the forward and backward driving of the car.
5. Under the condition of outputting the same amount of braking torque, the mass and size of the disc brake is smaller than that of the drum type.
6. The friction linings of disc brakes are easier to replace after they are worn out than drum-type friction linings, the structure is simpler, and the maintenance is easy.
