  • Vibration damping brake piston for a motor vehicle
    Patent number: 5492202
    Abstract: A motor vehicle disc brake assembly includes a caliper (12) supporting a pair of friction elements (32,33) to be applied against opposite sides (35,37) of a rotor (14). The caliper (12) forms a cylinder bore (18) in which a brake piston apparatus (40) is slidably mounted to be actuated by hydraulic or other fluid pressure from a master cylinder (20). The brake piston apparatus (40) includes a first piston member (46) and a second piston member (60) disposed within the cylinder bore (18) and having a compliant member (82) disposed therebetween. The compliant member (82) substantially isolates the first piston member (46) from vibrations generated by friction element contact with the rotor (14), substantially eliminating operator detectable tactile vibrations.
