Abstract
An automotive braking system controls the flow of pressurized brake fluid from a tandem master cylinder to several wheel brakes via a pair of braking circuits. Each circuit features a pressure relief line having, in series, a normally-closed valve, low-pressure accumulator, check valve, pump, damping chamber, and throttling orifice. A bypass line including a normally-closed bypass valve that is operated to interconnect the pressure relief lines of the first and second braking circuits proximate to the suction side of the pump, preferably downstream of the wheel brake outlet valves between the low-pressure accumulator and the check valve, selectively feeds fluid from one braking circuit to the other braking circuit to thereby reduce system response time when, for example, one or more wheel brakes driven by the other braking circuit is actuated to enhance vehicle traction or stability.
