PROBLEM TO BE SOLVED: To reduce defect occurring in changeover from a first pressurized state to a second pressurized state in such a state that a brake is operated.SOLUTION: A hydraulic brake system is configured so that a controller 30 activates by switching of a brake switch 162 from OFF to ON; when switching a master cylinder 16 from a first pressurized state to a second pressurized state in such a state that a brake operation member 14 is trodden, a second pilot pressure is increased by control of a hydraulic pressure adjustment device in the first pressurized state; and after switching of a regulator 24 from a first pressure adjustment state (master pilot) to a second pressure adjustment state (linear pilot), switching of a low pressure source cutoff valve 76 from an open state to a closed state and that of a communication switching valve 72 from the closed state to the open state are performed, respectively.SELECTED DRAWING: Figure 5 |
