Provided is a brake control device comprising a manual hydraulic pressure source and a powered hydraulic pressure source which serve as the hydraulic pressure supply sources for supplying hydraulic pressure to the wheels. A hydraulic actuator comprises an X-pipe having a first flow passage for supplying the working fluid from the manual hydraulic pressure source to the wheel cylinders of the front-left and rear-right wheels, and a second flow passage for supplying the working fluid from the manual hydraulic pressure source to the wheel cylinders of the front-right and rear-left wheels. The powered hydraulic pressure source supplies working fluid to the wheels using the first and second flow passages. A flow passage system including the first flow passage and a flow passage system including the second flow passage can be isolated by means of an isolation valve. The hydraulic actuator is provided with a regulating part for regulating the state of supply of working fluid in such a way as to reduce the difference between the state of supply of working fluid in either the first flow passage or second flow passage in which the working fluid flows in through the isolation valve, and the other state of supply of working fluid in which the working fluid does not pass through the isolation valve. The regulation part is provided in order to enhance the braking sensation by suppressing the generation of a disparity in pressure difference and response time between the first and second flow passages. |
