Zusammenfassung:	PURPOSE:To avoid wheel lock and secure sufficient braking force by connecting the piston front side liquid chamber of a proportioning valve with a reserver through a normally open selector valve, and by closing the selector valve at the time of No.1 decompression. CONSTITUTION:Liquid pressure from a master cylinder M/C is supplied to the wheels via control modulators M1, M2 by a control device ECU, wherein supply to the rear wheels is especially made through a proportioning valve PCV. The front side liquid chamber 11 of a valve piston 5 of PCV is connected with a reserver 13 via a normally open selector valve 12. The valve piston 5 is held in the current position by closing the selector valve 12 at the time of No.1 decompression due to skid sensing. The rear wheel brake liquid pressure is held at the current liquid pressure to prevent drop of the braking force on a split path, and thus a sufficient braking force is obtained.
