Abstract
The invention provides a lightweight brake drum ( ) having a lightweight, tubular inner member ( ), a length of wire ( ) wrapped around the inner member ( ) and an outer shell ( ). The inner member ( ) and the outer shell ( ) are made of a lightweight material. Typically, multiple layers of length of wire ( ) are wrapped around the inner member ( ) to support and inhibit expansion of the inner member ( ). Since the length of wire ( ) provides support against expansion, the inner member ( ) and the outer shell ( ) can be made of lightweight materials.
