Abstract
A disc brake assembly (10) having an actuation piston assembly 36 which responds to a hydraulic fluid to provide a force for moving brake pads (42, 44) into engagement with a rotor (12). The actuation piston assembly (36) has an elastomeric ring (66, 166, 266, 366) through which the force is transmitted to a brake pad (42) to attenuate any vibrations that may be created during a brake application and as a result a reduction in audible sound.
