Abstract: A disc brake assembly having a guide pin disposed in a bore of an anchor bracket such that a guide pin axis is offset relative to a bore axis whereby there is provided at least one defined point of contact between only a portion of the guide pin and a portion of an inner surface of the bore. The guide pin includes at least one slot having a member, which is formed separate from the guide pin, and disposed therein to bias the guide pin in the bore thereby offsetting the guide pin axis relative to the bore axis. The member includes a first member formed from an elastomeric material and a second member formed from a metal material, wherein the second member is configured to retain the member in the slot.

Abstract: A disc brake assembly having a guide pin disposed in a bore of an anchor bracket such that a guide pin axis is offset relative to a bore axis whereby there is provided at least one defined point of contact between only a portion of the guide pin and a portion of an inner surface of the bore. The guide pin includes a groove formed therein, the groove defines a groove axis which is offset relative to the guide pin axis, and a resilient member is disposed in the groove which is operative to bias the guide pin in the bore such that the guide pin axis is offset relative to bore axis to provide the at least one defined point of contact between only a portion of the guide pin and a portion of the inner surface of the bore.

Abstract: A damping element for attenuating hydraulic pressure pulses is integrated into a hydraulic chamber of a motor vehicle hydraulic system. The damping element includes a end cap support body and a membrane that fits over a portion of the support body. The membrane has a first side facing towards a source of hydraulic fluid and a second side facing away from the hydraulic fluid source. At least one space is provided between the second side of the membrane and the end cap support body to allow for deformation of the membrane under hydraulic pressure. The membrane has a collar with a lip seal provided for fitting into place on the wall of the hydraulic chamber. At least one second space for receiving hydraulic fluid is defined between the lip seal and a region of the membrane opposite the lip seal.
