Brake lining wear indicator gauge

A brake lining wear indicator gauge to be coupled to a brake camshaft of a brake adjusting mechanism wherein the camshaft has an end and is coupled to a slack adjustment lever having a cover plate, the camshaft end, the slack adjustment lever and the cover plate having respective alignment reference points, said gauge comprising a first side and a second side sharing a common outer periphery and a common central aperture for coupling said gauge to the camshaft end, said gauge indicating brake lining wear to a person without the use of a separate cooperating plate once said gauge is coupled to the camshaft end, said outer periphery being circular and having two adjacent notches forming a start-cycle pointer therein to be aligned with one of the respective alignment reference points at the start of the brake lining wear cycle, said outer periphery also having a third notch and a fourth notch therein, said first side having calibrations indicated by numerals and lines adjacent said outer periphery between said start-cycle pointer and said third notch and between said start-cycle pointer and said fourth notch, said numerals appearing in descending order from said start-cycle pointer to said third notch and from said start-cycle pointer to said fourth notch, said numerals and lines corresponding to the amount of brake lining wear.
