Abstract
A cylindrical brake drum including a flanged end and an open end having a squealer band in the shape of an annular ring 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 into the squealer band and the outside surface of the brake drum where the chill fins are generally of a constant height with respect to the outside surface and then moving axially outward decrease in height to meet the outside surface and cause any casting porosities to move to a central region of the squealer band thereby reducing drum cracking due to localized hot spots thereby greatly improving the brake drum fatigue strength while minimizing the increase in overall weight and facilitating ease of manufacture.
