Car brake shoe is a component of a vehicle's braking system, typically made of metal materials such as steel, aluminum, or cast iron with a friction material covering. They are installed in drum brake systems, in close coordination with the brake drum, to generate braking force through friction to slow down or stop the vehicle. Brake shoes are usually arc-shaped to fit the size and shape of the wheel and are designed to wrap around the outer surface of the brake drum to provide optimal braking performance.

Compared to traditional drum brakes, brake shoes offer faster and more precise brake response, and shorter braking distance, as they can easily make better contact with the brake drum.

Due to the close coordination of brake shoes and the brake drum, they offer stronger braking force than traditional disc brakes, making the brakes more stable and reliable. Brake shoe performance directly affects the braking ability and safety of the vehicle, so they must have characteristics of wear resistance, heat resistance, and durability. Brake shoes usually require frequent replacement to ensure optimal braking performance. Good brake shoes typically have excellent friction coefficient and low braking noise.
