Provided is a brake device capable of specifying a fluid leakage portion while generating braking force. Brake fluid is supplied to a first oil passage (an oil passage (11P), a discharge oil passage (13P)) and a second oil passage (an oil passage (11S), a discharge oil passage (13S)) by a pump (7), a communication valve (23P) and a communication valve (23S) are alternately driven to be open or closed a plurality of times, and on the basis of the magnitude of a detection value detected by a fluid pressure sensor (92P) and a fluid pressure sensor (92S) during the driving for opening/closing, and the occurrence of fluid leakage of the brake fluid in the first oil passage or the second oil passage is detected. |
