Abstract
There are provided a master cylinder M and proportional pressure intensification valves V V for each drawing a boosting hydraulic pressure in proportion to an output hydraulic pressure outputted from the master cylinder M from a source of hydraulic pressure S into a hydraulic pressure boosting chamber wherein one of pairs of front wheel brakes Bfa, Bfb and rear wheel brakes Bra, Brb connects to output ports 1 , 1 of the master cylinder M, and the other pair connects to the hydraulic pressure boosting chambers of the respective proportional pressure intensification valves V V Accordingly, it is possible to provide a vehicle braking system comprising proportional pressure intensification valves for generating a boosted hydraulic pressure intensified in proportion to an output hydraulic pressure outputted from a master cylinder without any increase in unsprung load of the vehicle.
