Abstract
Guide pins for retaining a caliper in an anchor of a disc brake assembly. The guide pins are characterized by a cylindrical body having a first end and a second end with a first diameter section that extends from the first end separated by a shoulder from a second diameter section that extends from the second end. The cylindrical body has a threaded axial bore that extends from a face on the second end toward the first end. A bolt has a shaft with threads thereon which mate with the threaded axial bore in the cylindrical body. A bushing is concentrically located on the shaft and in a corresponding axial opening in an ear that extends from the anchor. Torque applied to the bolt acts on and brings the bushing into engagement with the face on the second end of the cylindrical body however as the bushing has a greater length than the width of the axial opening of the ear, a desired gap is developed between a head on the bolt, the second end and the ear. Because of the gap, the bolt may freely rotated in the axial opening when the torque is terminated to realign the cylindrical body in a bore in the support member and as a result axial movement of the caliper is not substantially inhibi…
