Hub brake

(1)
A hub brake is a bicycle braking system that uses a brake drum and brake pads mounted on the wheel hub to achieve braking. The working principle of this brake is to slow down or stop the rotation of the wheel through the friction between the brake pads and the brake drum. Hub brakes usually include a brake drum that can rotate with the bicycle wheel hub, and brake pads that brake the brake drum.
