PROBLEM TO BE SOLVED: To improve the practicality of a hydraulic brake system including a master cylinder and regulator.SOLUTION: After a manipulation of a brake manipulation member is initiated, when a first state (manual pilot state) is changed to a second state (linear pilot state), before feedback control that is control of a second pilot pressure Pin the second state is initiated, a working fluid is fed (with a first set current I) to a second pilot pressure chamber with a valve body abutted on a pilot piston. Thereafter, the valve body is separated from the pilot piston. The working fluid is fed to the second pilot pressure chamber with a feed rate (a second set current I), that is larger than a feed rate employed when the working fluid is fed with the valve body abutted on the pilot piston, until an adjustment pressure Preaches a target hydraulic pressure P.SELECTED DRAWING: Figure 6

    【課題】マスタシリンダおよびレギュレータを備えた液圧ブレーキシステムの実用性を向上させる。【解決手段】ブレーキ操作部材の操作が開始された後に第1状態(マニュアルパイロット状態)から第2状態(リニアパイロット状態)に切り換える場合、第2状態における第2パイロット圧PPLT2の制御であるフィードバック制御の開始前に、弁体とパイロットピストンとを当接させた状態で第2パイロット圧室に一旦作動液を(第1設定電流ISLA1で)供給し、その後、弁体とパイロットピストンとを離間させて調整圧PSRVが目標液圧PSRV*に達するまで、弁体とパイロットピストンとを当接させた状態で作動液を供給する際の流量より大きな流量(第2設定電流ISLA2)で第2パイロット圧室に作動液を供給する。【選択図】図6
