The thermal expansion of the brake disc along the thickness direction is very small, which will not increase the brake clearance significantly as the brake drum does, resulting in excessive brake pedal travel; It is easy to realize automatic clearance adjustment, and other maintenance and repair operations are relatively simple.

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.
