Abstract
A brake wear indicator includes a prong and at least one flange that vibrates when the prong engages a rotating disc or drum. The brake wear indicator comprises a generally U-shaped spring clip with one end secured to a friction element and the other end terminating in the prong. A pair of friction elements are engageable with the disc or drum to retard rotation thereof and are worn to a predetermined dimension at which the prong engages the rotating disc or drum in order to vibrate the flange, thereby generating an audible warning signal. In a disc brake the flange on the brake wear indicator extends into a space defined below a bridge portion of a caliper which urges the friction elements into engagement with the disc and above the friction elements and disc.
