Abstract
An anti-lock hydraulic brake system is disclosed with a flow control valve in the brake line. To prevent the flow control valve from performing its control function during a normal braking operation, a retaining piston works in conjunction with a spring such that the retaining spring bears against a piston of the flow control valve and retains the flow control valve piston in its initial position during normal braking operation. The retaining piston also serves as a valve closure member for a valve in the return line.
