PURPOSE:To prevent a braking peak torque from being raised at the time of a rapid braking, by providing an orifice in a hydraulic pressure conduit leading to a duo-servo type rear brakes operated through a deceleration-sensing type hydraulic pressure controlling valve. CONSTITUTION:A deceleration-sensing type hydraulic pressure controlling valve 33 is provided between a master cylinder 36 and duo-servo type rear brakes 34, 35, and an orifice 23 is provided in a hydraulic pressure conduit. Accordingly, since the hydraulic pressure fed to the duo-servo brake can be prevented from being rapidly raised at the time of rapid braking in a loaded condition even when the movement of the deceleration-sensing valve is delayed, the braking peak torque is also prevented from being raised. |
