Description:
A drum brake is a brake that uses friction caused by a set of
shoes or pads that press outward against a rotating
cylinder-shaped part called a brake drum.
The term drum brake usually means a brake in which shoes press
on the inner surface of the drum. When shoes press on the
outside of the drum, it is usually called a clasp brake. Where
the drum is pinched between two shoes, similar to a conventional
disc brake, it is sometimes called a pinch drum brake, though
such brakes are relatively rare. A related type called a band
brake uses a flexible belt or "band" wrapping around the outside
of a drum.
The brake drum is generally made of a special type of cast iron
that is heat-conductive and wear-resistant. It rotates with the
wheel and axle. When a driver applies the brakes, the lining
pushes radially against the inner surface of the drum, and the
ensuing friction slows or stops rotation of the wheel and axle,
and thus the vehicle. This friction generates substantial heat.
