ABSTRACT:
A vehicle braking system includes a pair of valve devices which compensate for variations in wheel load for each of the rear brakes. The valve devices are controlled by suspension travel through a resilient linkage assembly, but because the suspension is stiffer in roll than in bounce, the linkage is desirably more sensitive in roll. The resilient linkage includes a pair of torsion bars, each of which has a crank arm at one end and a bearing support adjacent to the crank arm. Each crank arm is connected to a respective suspension component, the torsion bars being arranged so that the reaction at the bearing support provides the main control force for the respective valve while the other end of the torsion bar is connected to the other valve to provide a compensating force which is subtractive in the bounce mode but additive in the roll mode.
