A drum brake is a brake in which brake shoes with lining (friction material) attached to them are pushed by hydraulic pistons against the inner surface of a drum rotating together with the axle. This generates friction, which converts kinetic energy into heat and slows or stops the drum and the attached wheel. Drum rotation helps to press the shoes and the lining against the drum with more force, offering superior braking force in comparison with disc brakes. 
brake shoe is one of the most important part in the drum brake system .
