A BRAKE DRUM Abstract of the Disclosure A brake drum includes a cylindrical braking drum having a flange end and an opened end and including a plurality of generally axially extending fins around an exterior surface thereof. Each of the fins has radially extending side walls which diverge along the length thereof from the opened end to a widest distance therebetween at a predetermined location from the opened end and converged along the length thereof from the predetermined location to the flange end . Accordingly, adjacent side walls of adjacent fins define a space therebetween which has its narrowest portion at the predetermined location. A steel band is secured to and encircles the braking drum at the predetermined location. The steel band cooperates with the adjacent side walls and the exterior surface of the braking drum to define a cooling air channel at the narrowest portion of each of the spaces.
