The Role Of Brake Shoes

Brake shoes play a vital role in the braking system of automobiles. It is the core component of drum brakes, and it realizes the braking function of the vehicle by cooperating with the brake drum. When the driver steps on the brake pedal, the brake shoes expand outward under the action of hydraulic or air pressure, and produce friction with the inner wall of the brake drum, thereby generating braking force to slow down the car until it stops. ‌

Brake shoes are usually composed of friction materials, backing plates, springs and other components. Its working principle is to generate heat through friction, convert the kinetic energy of the vehicle into thermal energy, thereby achieving vehicle deceleration and stopping. During maintenance and replacement, it is usually necessary to use special tools to remove the wheel hub cover, pull out the cotter pin, remove the crown nut safety ring, etc., so as to more conveniently approach and replace the brake shoes.
