Abstract
A composite brake drum for use in a drum brake assembly includes a one-piece mounting flange and shell and a liner cast integrally in a shell portion thereof. The method for forming the composite brake drum of this invention includes the steps of: (a) providing a generally flat sheet of a first material; (b) forming the flat sheet into a generally flat circular blank; (c) subjecting to the blank to a series of metal forming operations to produce a one piece mounting flange and shell; and (d) casting a liner formed from a second material within the one-piece mounting flange and shell to thereby produce the composite brake drum.
