This vehicle brake system 1 is equipped with a mutually connected master controller 30 and first and second sub-controllers 40, 41, and an output cut-off control unit 200. Each of the controllers includes: a braking force calculation section for calculating the braking force of the electric brake; a self-determination section for determining whether or not the controller itself is normal; and an other-determination section for comparing the braking force calculation results of the controllers to determine whether the other two are normal. Upon determining that the master controller is not normal, the output cut-off control unit cuts off the output of the master controller, the determination being made on the basis of the self-determination result made by the master controller, the self-determination result and determination result regarding the master controller made by the first sub-controller, and the self-determination result and determination result regarding the master controller made by the second sub-controller.
