Abstract
An improved method for producing a brake drum which balances a brake drum defining an inner surface and an axis. Balancing specifications are determined which correct an imbalance of the brake drum about the axis. Material is removed from the inner surface, which forms a cylindrical surface preferably defining a braking surface of the brake drum, to balance the brake drum according to the balancing specifications. It is a further feature of the invention to remove material surrounding a pilot hole initially formed in the brake drum, wherein the removal of the material also correlates to the balancing specifications.
