摘要

An anti-lock vehicle brake system includes a source of fluid pressure, a wheel brake connected to source of fluid pressure and an anti-lock control valve for relieving pressure at the brake. Sensing and control apparatus are provided for positioning the control valve. A restriction apparatus limits the flow of fluid pressure to the brake. A fluid flow control is provided intermediate the anti-lock control valve and the restriction apparatus for control of the restriction apparatus.
