Generally, there is no friction potential, so the brake efficiency is less affected by the friction factor, that is, the efficiency is more stable; The efficiency decreases less after water ingress, and it can return to normal after only one or two times of braking; Under the same output braking torque, the size and mass are smaller than that of drum brake;

The brake disc is a very important part of the brake system. A good brake disc has stable braking, no noise and no jitter. Many DIY players do not want to replace the brake disc by themselves without certain professional knowledge, because the original brake disc has been tested by many professional engineers and can fully withstand the braking force of their cars.
