[Problem] To provide a vehicle brake hydraulic control device whereby it is possible to improve brake responsiveness when a brake is re-operated by a driver during ABS control, without it feeling unnatural to the driver. [Solution] A vehicle brake hydraulic control device is equipped with a wheel speed acquisition unit that acquires wheel speed and a vehicle body deceleration calculation means for calculating a vehicle body deceleration on the basis of the wheel speed. If a condition is satisfied in which vehicle body deceleration continues to stay at a low rate of less than or equal to a predetermined threshold value for a certain duration of time, the pressure increasing rate in pressure increasing control is changed so as to be higher than before the condition was satisfied. [Effect] The caliper-side brake hydraulic pressure (CAL pressure) can be quickly brought close to the master-cylinder-side hydraulic pressure (M/C pressure). Therefore, it is possible to improve brake responsiveness when brakes are re-operated by a driver during ABS control, without it feeling unnatural to the driver.
