Abstract
A cylindrical brake drum including a flanged end and an open end having a radially extending annular extension ring acting as a squealer band and a multiplicity of chill fins irregularly spaced one to another and/or relative to a plurality of equally spaced airflow channels where the chill fins are cast as part of the extension ring and the outside surface of the brake drum where the chill fins are of a substantially constant height relative to the brake drum and act to reduce the size and number of any casting porosities and further move the porosities away from the friction surface of the brake drum thereby improving fatigue strength. A multiplicity of cooling fins are formed on the inboard side of the extension ring. In an alternative embodiment, the extension ring can be formed as a wing which axially extends from the brake drum having a multiplicity of chill fins formed on its outer surface.
