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.
