A vehicle hydraulic brake system, including: a brake operating member; a master cylinder including (i) an output piston for generating a hydraulic pressure in a pressurizing chamber, (ii) an input piston, and (iii) a rear chamber provided rearward of the output piston; a hydraulic brake provided for a wheel and actuated by the hydraulic pressure to reduce rotation of the wheel; a rear-hydraulic-pressure control mechanism connected to the rear chamber; and a controller including a master cylinder pressure estimator that estimates the hydraulic pressure in the pressurizing chamber and that includes a contact-state estimator that estimates whether the input piston and the output piston are in a contact state; and a contact-state master cylinder pressure estimator that estimates the hydraulic pressure in the pressurizing chamber based on a movement amount of the input piston when the input piston and the output piston are estimated to be in the contact state.
