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

    【課題】ブレーキ操作がなされた状態のままで第1加圧状態から第2加圧状態に切り換える際の不具合を軽減することを課題とする。【解決手段】ブレーキスイッチ162がOFFからON切り換えられたことにより制御装置30が起動し、ブレーキ操作部材14が踏み込まれた状態でマスタシリンダ16を第1加圧状態から第2加圧状態に切り換える場合、第1加圧状態のまま液圧調整装置を制御して第2パイロット圧を増加させ、レギュレータ24が第1調圧状態(マスタパイロット)から第2調圧状態(リニアパイロット)に切り換わった後、低圧源遮断弁76の開状態から閉状態への切換、および、連通切換弁72の閉状態から開状態への切換をそれぞれ行うように構成する。【選択図】図5
