A vehicle brake system for giving an excellent brake feeling to a driver includes: a stroke detector configured to detect a stroke of a brake pedal; a brake fluid pressure generator including a motor actuator and configured to generate a brake fluid pressure by operation of the motor actuator, and a controller configured to control the operation of the motor actuator on the basis of a detected value by the stroke detector. The controller has a base required-deceleration map for obtaining a base required-deceleration associated with a detected value by the stroke detector; a responsive-feeling required-deceleration map for obtaining a responsive-feeling required-deceleration associated with the detected value by the stroke detector; and a phase-lag processor applying phase-lag processing on the responsive-feeling required-deceleration, and control the operation of the motor actuator on the basis of the required-deceleration and the responsive-feeling required-deceleration applied with the phase-lag processing.
