A vehicle brake hydraulic pressure control apparatus includes a pressure increasing section, a holding section, and a determination section and wheel speed sensors. The pressure increasing section increases a brake hydraulic pressure by driving a motor. The holding section holds a brake hydraulic pressure. The determination section determines as to whether or not the motor is malfunctional. The wheel speed sensors detect as to whether or not a vehicle which is at a halt starts to move. If the wheel speed sensors detect that the vehicle starts to move while the holding section is executing a holding control, the pressure increasing section executes a hydraulic pressure re-increasing control by driving the motor, and the determination section determines as to whether or not the motor is malfunctional based on a detection result by the wheel speed sensors after the brake hydraulic pressure is started to be increased by the hydraulic pressure re-increasing control.
