A slide pin bushing 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 pads are carried by the disc brake caliper assembly, and an actuation means is provided for selectively moving the brake pads axially toward and away from one another so as to selectively frictionally engage the rotor. An elastomeric slide pin bushing is disposed in a non-threaded opening formed in the caliper. The slide pin bushing includes an outer end section, an intermediate section, and an inner end section. The intermediate section has an inner surface and an outer surface. The inner surface is provided with at least one groove formed therein. The groove is provided with a first end and a second end. The first end is located near the outer end section and the second end located near the inner end section. At least one of the first end and the second end of the slide pin bushing terminates within the intermediate section so that the groove does not extend into the associated outer end section and inner end section of the slide pin bushing at the at least one of the first end and the second end. A generally rigid sleeve is disposed within the slide pin bushing. The sleeve includes an outer surface which engages the inner surface of the slide pin bushing. A pin extends through the sleeve to secure the caliper to the anchor plate for sliding movement relative thereto.
