Abstract
A composite brake drum particularly adapted for motor vehicle applications. The brake drum includes a reiforcement assembly enclosed within the cylindrical portion of the drum. The reinforcement assembly is preferably made from steel wire stock and includes a plurality of circular loops spaced axially within the brake drum cylindrical portion. Axially extending locator wires are mechanically fastened to the reinforcing loops and serve to locate the loops. End portions on the locator wire contact only one of the mold halves forming the mold cavity and enable the device to be essentially self-locating without crossing the parting line of the mold. By not crossing the parting line, the position of the loops is maintained within acceptable tolerance limits from the finished friction surface of the drum.
