The braking device is the system to hinder vehicle movement ,or produce the stop force to the auto’s moving.Except for the slow speed devices,most of them is using the friction between fixing element and rotating element to make braking torque.

At present,the friction braking device for autos has two kinds with drum and disc based on rotating elements’ differences.Drum braking device’s rotating element is brake drum,and works on it’s inside surface.The disc braking device’s rotating element is round disc shape brake rotor,it works on it’s both side surface.

The brake disc has better heat radiation ability than brake drum.When at frequent braking conditions,braking failure will not happen.

The changes of the size of brake disc after it’s heating won’t increase the distance of brake pedal to work.

The reacting of the brake system is fast,it can work with high frequency braking to meet the standard of ABS system.

The disc has no auto tight braking like the drum,so the brake force is even for the right and left wheel.
