ABSTRACT:
An improved method for final balancing a brake drum determines the location and length of a first constant depth cut and a second constant depth cut along the squealer band which are necessary to correct the imbalance, and using a cutting machine, makes the first and second constant depth cuts at the predetermined location and for the predetermined length along the squealer band to produce a final balanced brake drum. Preferably, the cutting machine is a milling machine which produces a plunge type entrance/exit cut. It is a further feature of the invention to provide a feather type entrance/exit cut to reduce the stress concentrations, and produce a cosmetically more appealing final balanced brake drum.
