Abstract
In a hydraulic brake system the fluid slack is maintained at a predetermined volume by a flow control valve that is positioned between a fluid reservoir and a slack adjusting cylinder. The flow control valve closes the fluid path to the reservoir after a chamber in the cylinder fills with a predetermined amount of slack fluid. The flow control valve can be held open with a detent mechanism to permit servicing of the brake system. The detent is automatically released when the brakes are applied.
