Patent ID: 8235473

Claim:
A motorcycle brake system comprising: a first master brake cylinder for hydraulically activating a first brake circuit; a second master brake cylinder for hydraulically activating a second brake circuit; a pump having a suction side and a pressure side that is connected to the first brake circuit and the second brake circuit; each brake circuit including: an inlet valve and an outlet valve for controlling brake slip of a wheel brake; a low-pressure accumulator connected downstream of the outlet valve on a return line that leads to the suction side of the pump; an isolating valve configured to selectively connect an associated master brake cylinder to the pressure side of the pump and to a wheel brake; a switchover valve configured to selectively connect the associated master brake cylinder to the suction side of the pump; and a valve circuit between the pump and the associated master brake cylinder, the valve circuit configured to prevent pressure generated by the pump from reacting on an activated master brake cylinder.
