ABSTRACT:
A composite brake drum for a motor vehicle or the like is comprised of a cast metal drum section, a stamped steel drum back, and a cast metal mounting face. The drum section and mounting face are preferably formed of cast iron. The composite drum of the invention provides a reduction in weight and in the amount of machining required as compared with a full cast brake drum. At the same time, the composite brake drum of the invention permits an increase in the thickness of the mounting face as compared with conventional composite brake drums, allowing motor vehicle manufacturers to use the same hubs and keep the vehicle track the same regardless of whether a particular vehicle includes a disc/drum or a disc/disc brake system.
