Abstract: A tape correction plate and method of using the correction plate to correct for lateral runout of a disc brake rotor is described. The tapered correction plate is installed between the hub and brake rotor of an automobile such that the thinnest portion of the correction plate is aligned with the angular position on the hub and rotor corresponding to the maximum lateral runout. The mounting geometry of the correction plate may include any one of a number of configurations including circular openings, slotted openings having a smooth or gear-like perimeter, or an outer perimeter defining a gear like shape or open-ended "half slots." Each type of mounting geometry is suitable for mating with existing lug patterns while enabling adjustment of the angular orientation of the correction plate with respect to the hub and rotor. The correction plate may also consist of one washer or a number of washers with appropriately varying thicknesses that are arranged to correct runout.
