How Brake Shoe Work?
Brake shoes convert the kinetic energy of the car to thermal energy by use of "friction". When a brake shoe is heated up in contact with a drum, it starts to transfer small amounts of friction material to the drum. The brake drum (both now with friction material on), will then "stick" to each other to provide stopping power. The friction of the shoe against the drum is responsible for the majority of stopping power.During braking, a wheel cylinder in the drum brake system forces the brake shoes outward and against the spinning brake drums.This creates friction, slowing the drum and as a result, the vehicle
