The minimum wear thickness, 1.215 in., is cast into each disc hub. This is a minimum wear dimension and not a refinish dimension. If the thickness of the disc after refinishing will be 1.230 in. or less, it must be replaced. Refinishing is required whenever the disc surface shows scoring or severe rust scale. Scoring not deeper than 0.015 in. in depth can be corrected by refinishing.
Some discs have an anti-squeal groove. This should not be mistaken for scoring.
