摘要（英）：

The utility model relates to a pneumatic contraction-type drum brake assembly. The drum brake is provided with rotary sealing members which are adhered and connected to two opposite axial sides of a hub central area and are used for sealing a hub and a brake drum. Side plates of a shell and the brake drum are taken off, so that the two rotary sealing members can be closed so as to be conveniently replaced during maintenance, and the hub does not need to be taken off.
