An electrohydraulic brake controller comprises at least two first and two second output ports for at least four wheel brakes, s hydraulic pressure source, a first electronic open-loop and closed-loop control unit, a second electronic open-loop and closed-loop control unit, an inlet valve for each first and second output port, and an outlet valve for each first and second output port. A pressure chamber is connected via a first pressure activation valve to a brake line section to which the at least four inlet valves are connected. If the first electronic control unit fails, an electromechanical actuator is activated by the second electronic control unit and builds up pressure to actuate the wheel brakes. If the second electronic control unit fails, the electromechanical actuator is activated by the first control unit and builds up pressure to actuate the wheel brakes.
