ABSTRACT:
An improved structure for a slide pin bushing and boot seal assembly for use in a vehicle disc brake caliper assembly adapted to selectively frictionally engage a rotor connected to a vehicle wheel includes an anchor plate adapted to be secured to a stationary component of the vehicle, and a caliper secured to the anchor plate for sliding movement relative thereto. A pair of brake shoes are carried by the disc brake caliper assembly, and an actuation means is provided for selectively moving the brake shoes axially toward and away from one another so as to selectively frictionally engage the rotor. The slide pin bushing and boot seal assembly is carried by the disc brake caliper assembly and includes a slide pin bushing formed from a relatively hard resilient elastomeric material and a boot seal formed from a relatively soft flexible elastomeric material and joined to one end of the slide pin bushing to define an integral one-piece unit. A slide pin extends through the boot seal and at least a portion of the slide pin bushing for securing the caliper to the anchor plate for sliding movement relative thereto.
