Abstract
A vehicle braking system has a master cylinder, a first brake associated with a front wheel of the vehicle and a second brake (11) associated with a rear wheel of the vehicle, the master cylinder being connected to the first and second brakes in a common circuit. The second brake includes brake actuator (10) with a valve (30, 35) which will vary the rate at which fluid pressure is applied to the brake actuator (10) at a predetermined brake pressure, a spring loaded lever (50) acts on the valve (30, 35) to set the predetermined pressure at which the rate of application of pressure is varied and a linkage mechanism (70) varies to loading of the lever (50) to vary the predetermined pressure in proportion to the load applied to the rear wheel with which the brake (11) is associated.
