When braking, the oil pressure is used to push the brake shoes to touch the inner edge of the brake drum, and the friction generated by the contact is used to restrain the rotation of the tire so as to achieve the purpose of braking. The drum brake is composed of a brake floor plate, a brake pump, a brake shoe and other relevant connecting Rod, a spring, a pin and a brake drum. Currently only commonly used in the rear wheel.
