Abstract
An improved structure for a brake drum adapted for use in a drum brake assembly includes a generally closed outer end, a generally axially extending cylindrical main body, and an open inner end. The closed outer end of the brake drum includes a centrally located wheel spindle opening formed therein, and a plurality of lug bolt mounting holes spaced circumferentially around the wheel spindle opening. The cylindrical main body of the brake drum includes a plurality of generally axially extending raised ribs provided on an outer surface thereof. Preferably, the ribs define at least three distinct strengthened areas on the brake drum.
