In a drum brake, the part that carries the friction material and presses against the drum is called the what?

• A. Brake lining
• B. Brake pad
• C. Drum
• D. Brake shoe

Answer: (D)

In a drum brake, braking force comes from a curved piece inside the drum that carries the friction material on its outer surface. When hydraulic pressure is applied, the wheel cylinder pushes this piece outward so the friction material, or lining, presses against the inner surface of the spinning drum. That contact converts kinetic energy into heat and slows the wheel. The component that carries the friction material and presses on the drum is the brake shoe. The friction material is called the lining, brake pad is for disc brakes, and the drum is the rotating shell the shoes press against. So the brake shoe is the correct term.
