Abstract
A clip-type wear indicator suitable for use with a disk brake. The disk brake includes a rotor, a pair of slidable friction pads located on opposite sides of the rotor, the friction pads including a lining and a backing plate attached thereto and extending radially therefrom, a stationary support member radially spaced from the rotor and having a mating guide, and a caliper adjacent to the backing plates for urging the linings against the rotor. The clip is secured to the stationary support member when the upper, lower, left and right suppressing pieces are brought into elastic engagement with the mating guide on the stationary support member. The upper suppressing piece has a notch that is positioned so that when the caliper urges the lining against the rotor and edge of at least one of the backing plates is aligned with the notch when the lining is worn to such an extent that the friction pads should be replaced.
