What is the drum brake ah there is no detailed description of the motorcycle knowledge site can tell me
When the brake pedal is depressed, the force on the foot causes the piston in the brake cylinder to push the brake oil forward and generate pressure in the oil path. The pressure is transmitted through the brake oil to the brake cylinder of each wheel. The piston of the brake cylinder then pushes the brake pad outward to cause the brake pad to friction with the inner surface of the brake drum and produce enough friction to reduce the wheel speed, To achieve the purpose of the brake
Simply put, the drum brake is the use of brake drums within the static brake pads, to friction with the wheel rotation of the brake drum to produce friction to reduce the wheel speed of the brake device.
The brakes on the inside of the brakes are the position of the brake torque. In the case of obtaining the same braking torque, the diameter of the brake drum of the drum brake device may be much smaller than the brake disc of the disc brake. Therefore, large vehicles for heavy loads can only be equipped with drum brakes in a limited space for wheels to obtain a strong braking force.
Drum brakes have been used in the car for nearly a century, but because of its reliability and strong braking force, drum brakes are still deployed on many models (mostly on the rear wheels). Drum brake is by hydraulic will be installed in the brakes inside the brake pads to push out, so that the brake pads and wheel rotation with the friction inside the surface of the friction, and the effect of braking.
