ABSTRACT:
A brake drum generally cylindrically shaped having a substantially closed end forming a drum face and an open end with airflow channels formed in the outside peripheral surface of the brake drum in substantial alignment with a plurality of wheel hand hold openings and a squealer band positioned at the edge of the open end to improve cooling of the tire bead area of the wheel rim by increasing the airflow between the brake drum and the wheel rim thereby reducing the heat transferred from the brake drum into the wheel rim.
