Abstract
A guide pin (24) attached to a caliper (21) and located in a bore (28) of an anchor bracket or carrier member (22) in a disc brake (10). The carrier member (22) and caliper (21) move with respect to each other in response to a force developed by a piston for urging friction pads (18,20) into engagement with a rotor (12) to effect a brake application. The guide pin (24) is characterized by a head (36) having a shaft (38) extending therefrom into a bearing (62,64) which is located between the shaft (38) and housing surrounding the bore (28). The bearing (62,64) has dissimilar resistances to stiffness in a radial plane than in a tangential plane such that vibratory forces are attenuated and dynamic forces generated during a brake application are absorbed to maintain alignment between the friction pads (18,20) and rotor (12).
