To alleviate the sense of rejection in a brake pedal or a brake lever that arises when a long pressure decreasing mode or a long holding mode has continued in a hydraulic brake device equipped with an actuator that automatically regulates braking liquid pressure in a wheel cylinder of a vehicle without the intervention of an operation by a driver. According to the present invention, there is provided a brake control method for a hydraulic brake device equipped with an actuator that automatically regulates braking liquid pressure in a wheel cylinder of a vehicle without the intervention of an operation by a driver. At a time when the actuator of the hydraulic brake device operates automatically, the method includes: (a) a step of detecting whether pressure to the wheel cylinder is being increased; (b) a step of calculating a time period in which pressure to the wheel cylinder is not being increased; and (c) a step of increasing pressure and decreasing pressure to the wheel cylinder to an extent that has no impact on the braking force of the vehicle after the time period that has been calculated has reached a predetermined time.
