  • Noise attenuated anti-lock brake system
    Patent number: 5108159
    Abstract: A noise sensor for supplying a central processing unit of an anti-lock brake system with a noise signal corresponding to vibrations produced during braking. The central processing unit responds to the noise signal by supplying a control valve assembly with an operational signal which modulates the fluid pressure supplied to a wheel cylinder to create a predetermined fluid pressure frequency therein to nullify vibrations and correspondingly attenuate noise produced thereby.

  • Actuation piston for disc brake with vibration attenuator
    Patent number: 5014827
    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.
