Abstract

A hydraulic brake system includes: a brake hydraulic-pressure control device capable of controlling a hydraulic pressure in a brake cylinder of a hydraulic brake configured to reduce a rotation of a wheel, the brake hydraulic-pressure control device including (i) a piston, (ii) a hydraulic-pressure chamber provided opposite the piston, and (iii) a moving-force control device configured to apply a moving force to the piston and capable of controlling the moving force; and an air reducing device configured to control the moving-force control device to move the piston to reduce air in an air reduction target portion including the hydraulic-pressure chamber.
