ABSTRACT:
A brake drum that converts kinetic and potential energy into frictional heat without developing destructively high temperatures and provides such performance at a reduced weight with an increase in cooling effectiveness through the use of a squealer band positioned on the centerline of the drum braking surface along with axial cooling fins radiating therefrom and windows on the wraparound portion abutting mounting face.
