Patent ID: 7971941

Claim:
A motorcycle brake system comprising a hand-operated or foot-operated first master brake cylinder for a hydraulic actuation of a first brake circuit and with a hand-operated or foot-operated second master brake cylinder for a hydraulic actuation of a second brake circuit, the brake system further comprising an inlet and an outlet valve provided for brake slip control in each wheel brake of each brake circuit, a low-pressure accumulator arranged in each of the two brake circuits and being connected in each case downstream of the outlet valve to a return conduit, a pump with a suction side and a pressure side, the suction side being connected to the return conduit and the pressure side being connected to the respective associated brake circuit, the brake system further comprising a separating valve in each brake circuit which, in an open position, connects the associated master brake cylinder to the pump pressure side, and a change-over valve in a suction path of each brake circuit, which change-over valve, in an open position, connects the associated master brake cylinder to the suction side of the pump, wherein, at the beginning of a pump operation in one of the two brake circuits, the change-over valve ( 20 ) and the separating valve ( 19 ) associated with the brake circuit assume switching positions in which a reactive effect of pressure pulses generated by the pump ( 9 ) on the associated master brake cylinder ( 7 , 13 ) is diminished, wherein the change-over valve ( 20 ) assumes a closed switching position during the operation of the pump in the associated brake circuit.
