This invention relates to a one piece brake lining wear indicator that is a reversible circular dial. Calibration marks are included on both sides of the circular dial along with several accentuating notches on the outside circumference of the dial. When the dial is coupled to the splined end of a rotatable brake shoe camshaft that is equipped with manual or automatic slack adjusting levers, the dial acts as an indicator of the amount of brake lining wear that occurs inside the brake drum compartment.
