ABSTRACT:
A control mechanism is provided for a vehicle braking system of the kind in which a pair of pressure modulating valves have their performance modified during vehicle cornering only so that the brake on the inboard wheel receives less pressure than the brake on the outboard wheel. The control mechanism comprises a member which has four points forming the corners of a trapezium. The first two points, which are at the ends of one of the parallel sides of the trapezium, are connected to the suspension, the third point is connected to the valves, while the fourth point is constrained from vertical movement. During normal travel the member rotates freely about the third and fourth points so that there is no input to the valves. However, in cornering the vehicle roll causes the first and second points to move differently so that the third point also tends to move so altering the performance of the valves.
