The isolating layer is a layer of vibration-attenuating material. Alternatively, the isolating layer is a layer of material which has properties that prevent creep or sliding wear for at least one of the backup surfaces. The isolating layer is attached to the washers by bonding, use of adhesives or mechanical means.
