brake is a brake that uses friction caused by a set of shoes or pads that press
against a rotating drum-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.
