Nowadays, most vehicles, such as cars, motorcycles, or bicycles, use disc brakes. Regardless of the weather or riding conditions, the disc brake system can provide a stable braking effect.

A common design is to fix the disc in the wheel frame and run synchronously with the wheel frame. When the disc is clamped by the caliper, the disc that rotates with the axle is forced by the caliper to clamp the disc on one or both sides. The friction produces friction, so that the disc can decelerate, thereby decelerating the tire, achieving the effect of braking deceleration or braking stop.
