Braking Discs Brake Pads Brake Rotor Cooling For MTB Road Bike

When the disc brakes, it will produce high temperature, the disc will have the thermal expansion, the floating disc will swing slightly, make a proper angle, and have a most suitable friction surface with the brake pads to maintain the stability of the brakes. The area of the disk is increased, and the heat dissipation function of the disk is also provided.

The outer friction surface of the brake disc is separated from the inner bracket, and the middle is connected by a special non-rigid structure, that is, a floating coupling. In this way, the friction surface and the bracket become relatively independent force-receiving surfaces. When the friction surface is thermally expanded, the floating structure allows the friction surface to have a certain free longitudinal expansion space, thereby eliminating the condition of internal pulling stress between the bracket and the bracket. Keeping the friction surface will not be distorted due to uneven heating, making the brake more stable and reliable.
