First, the advantages of drum brake: this brake is relatively low in manufacturing cost, and it is also in line with the traditional design concept. If it is a four-wheeled car, it will appear because it will not.

With the same degree of cowardice, the load borne by the front wheel will account for about 75% of the whole vehicle, so the braking force of the front wheel is definitely much larger than that of the rear wheel, and the main function of the rear wheel is to assist braking, so it is very good.
In order to save costs better, car manufacturers usually choose the main braking method of front disc and rear drum, but for some heavy vehicles, because the whole speed is relatively high.

Low, and brake shoes are definitely much higher than disc brakes in durability, so heavy vehicles will still choose four-wheel drum design.

Disadvantages of drum brake: The disadvantages of drum brake should be the heat dissipation performance and braking efficiency. Because its braking force is not particularly good in stability, it is driven on different roads and braked.

The force will change differently, so it will be more difficult to control, and the loose parts of the eye plate will be poor, and a lot of holding capacity will be sold in the braking process, while the drum and brake block will be heated for a long time.

Different degrees of deformation will occur, which will easily lead to braking chattering and recession, and eventually lead to a serious decline in braking efficiency.
