のブレーキ液圧制御装置。 A master cylinder that generates hydraulic pressure corresponding to the pressing force on the accelerator pedal, a front brake that brakes the front wheels of the vehicle by receiving the hydraulic pressure supplied from the master cylinder via a front brake conduit, and a rear brake. A rear brake that brakes the rear wheels of the vehicle by receiving hydraulic pressure supplied from the master cylinder via a conduit, and a rear brake that is interposed in the middle of the rear brake conduit and responds to increasing changes in the pressing force of the accelerator pedal. A hydraulic pressure control mechanism that acts to reduce the rate of change in the hydraulic pressure supplied to the rear brake, which increases proportionally, after reaching a predetermined pressure, and a rear brake side hydraulic pressure upstream of the hydraulic pressure control mechanism. and the front brake side hydraulic pressure introduced through a branch pipe branching from the front brake pipe, and when the front brake side hydraulic pressure is higher than a predetermined pressure, brake fluid is supplied. a brake fluid pressure control valve having a conduit control mechanism section that operates to allow brake fluid to flow through the fluid pressure control mechanism and not through the fluid pressure control mechanism when the pressure is below a predetermined pressure. The brake fluid pressure control device for a vehicle is such that the rear brake conduit and the branch conduit are capable of communicating with each other via a communication path, and the communication path is connected to or connected to the communication path. A brake fluid pressure control device for a vehicle, characterized in that a passage opening/closing means for cutting off communication is provided.
