ABSTRACT:
An hydraulic braking system for vehicles comprises a single pedal-operated master cylinder, a selector valve assembly and a double-acting valve incorporated into a common housing, and an actuator for a brake on either side of the vehicle. A lever acts to close a diverter valve to cut-off the supply of fluid to the actuator on one side when the brake on the other side is to be applied, so that one brake is applied independently of the brake on the other side. Each actuator comprises a differential piston which works in a stepped bore to apply the brake, and when one of the valves closes, the lever simultaneously acts on the double-acting valve to increase the effective area of the actuator for the applied brake. A greater output torque is therefore obtained from the brake on one side when the brake on that side is applied independently than when the brakes on both sides are applied simultaneously.
