PROBLEM TO BE SOLVED: To provide a technology for easily exhausting air mixed in a vehicular brake device, without imposing a large burden on an occupant and a worker. SOLUTION: A hydraulic actuator 18 connects a master cylinder, a power hydraulic pressure source 16 and a wheel cylinder 24 so as to be capable of supplying a working fluid to the wheel cylinder 24 from the master cylinder and the power hydraulic pressure source 16. A control valve is arranged in a hydraulic pressure supply flow passage, and controls supply of the working fluid to the wheel cylinder 24 from the master cylinder and the power hydraulic pressure source 16. A brake ECU 100 controls driving of the power hydraulic pressure source 16 and opening-closing of the control valve. A temperature sensor 104 detects information correlated to the temperature of the working fluid. The brake ECU 100 controls the opening-closing of the control valve to communicate the power hydraulic pressure source 16 with a reservoir flow passage 72 by driving the power hydraulic pressure source 16 when the temperature detected by the temperature sensor 104 is larger than a predetermined value.
