- 1 - Abstract: A method of forming a brake drum includes the steps of casting an iron cylindrical brake drum with a flange end and an open end to include a plurality of generally axially extending fins around an exterior surface thereof. The cast- ing includes providing the fins with radially extending side walls which diverge along a length thereof from the open end to a widest distance therebetween at a predetermined location from the open end and converge along the length thereof from the predetermined location toward the flange end. Accordingly, adjacent side walls of adjacent fins define a space there- between having its narrowest portion at the predetermined location. A braking surface is machined about an interior surface portion of the cylindrical brake drum. A portion of the top of the fins is machined on either side of the predetermined locations to form a cylindrical array of seats each with a shoulder located inwardly of the predetermined locations. A steel band is formed and secured to the brake drum on the seat of the fins to encircle the brake drum at the predetermined location.
