Beginner's Guide: What Are Brake Drums and What Do They Do?
A brake drum is a cylindrical drum that is attached top the inside of a car’s wheel, and so rotates at the same speed as the wheel. The drum surrounds a set of brake shoes that are coated in materials that generate friction.When the brake pedal is pressed, these shoes are pushed outwards against the inner surface of the brake drum, generating friction and so slowing the car down.A brake drum is usually made of iron, rendering it resistant to wear.
