摘要： PURPOSE:To prevent vibrating force of hydraulic pressure in a bad path from being transmitted to a controlling valve by providing a spring between a piston for receiving the hydraulic pressure corresponding to live load and a piston for pushing hydraulic pressure controlling valve in the closing direction for force transmission. CONSTITUTION:A proportional pressure reducing valve 26 is provided between a master cylinder 10 and a rear wheel brake 16 and a first piston 23 for pushing said valve 26 in the closing direction is pressed by a second piston 27 through a spring 32.
