Brake hub, also known as brake drum or brake pan is a brake hub, is a brake device that relies on friction between the two to reduce the speed of wheel rotation. The working principle of the brake drum is a brake device that relies on friction between the two to reduce the speed of the wheel rotation. When the brake pedal is pressed down, the force of the foot will push the brake master pump forward and create pressure in the oil circuit. Advantages of brake hub: 1. There is an automatic brake tightening, so that the brake system can use a lower oil pressure, or use a brake hub with a diameter much smaller than the brake disc. 2. Easy installation of hand brake mechanism. Some models with disc brakes installed at the rear wheel will install a hub brake hand brake mechanism in the center of the brake disc. 3. The processing and composition of the parts are relatively simple, and the manufacturing cost is relatively low. Disadvantages of brake hub: 1. The diameter of the drum brake drum will increase after being heated, resulting in increased travel of the brake pedal, and it is easy to have a braking response that is not as expected. Therefore, when driving a vehicle with drum brakes, it is necessary to try to avoid continuous braking resulting in thermal decay of the brake pads due to high temperature. 2. The brake system responds slowly, and the stampede of the brake is less easy to control, which is not conducive to high frequency brake action. 3, the structure of complex parts, brake clearance must be adjusted, making maintenance is not easy.
