ABSTRACT:
A liquid pressure braking system for a vehicle has a master cylinder which is connected to the brake operating motor cylinder on each front wheel of the vehicle through a respective liquid pressure intensifier. Each intensifier has a differential area piston. The differential liquid pressure on the piston, which tends to close the valve and render the intensifier effective to increase the liquid pressure at its outlet as compared with its liquid pressure inlet, is opposed by a spring which reacts against a stepped plunger. The plunger projects towards a link 18 of a mechanism which interconnects suspension components of the two front wheels. Load transfer from the inboard front wheel during cornering increases the spring load applied to the piston of the intensifier that controls the supply of liquid pressure to that front wheel so that the valve of that intensifier remains open after closure of the valve of the other intensifier and the brake pressure that acts on that inboard front wheel is lower than the brake pressure that acts on the outboard front wheel.
