Advantages of drum brake
Drum brake drum is cheap and conforms to the traditional design. In the braking process of four wheel car, due to the inertia, the load of front wheel usually accounts for 70% to 80% of the total load of the vehicle. The front wheel braking force is larger than the rear wheel, and the rear wheel plays an auxiliary braking role. Therefore, in order to save cost, the car manufacturer adopts the brake formula of front disc and rear drum. However, for heavy vehicles, because the speed is not very high, the durability of brake shoes is higher than that of disc brake, so many heavy vehicles still use four wheel drum design.

The braking efficiency and heat dissipation of drum brake are much worse. The braking force stability of drum brake is poor. The braking force changes greatly on different roads, which is not easy to control. Due to the poor heat dissipation performance, a large amount of heat will be accumulated in the braking process. Under the influence of high temperature, the brake pad and wheel drum are easy to have extremely complex deformation, which is easy to produce the phenomenon of brake recession and chattering, resulting in the decline of brake efficiency. In addition, after the drum brake is used for a period of time, the gap of the brake shoes should be adjusted regularly, and even the whole brake drum should be removed to clean up the accumulated brake powder.
