Abstract
An hydraulic braking system is disclosed which comprises a fluid source and brake actuators, wherein a first master control valve is provided to supply substantially equal pressures to all brake actuators and additional control valves are provided to regulate pressures applied to respective ones of said brake actuators. The first control valve and the additional control valves are provided in series between the fluid source and the brake actuators so that operation of the master control valve allows equal hydraulic pressures to be applied to each actuator while the additional control valves allow individual brake regulation and in an emergency operation of the master control valve allows for automatic operation of all the actuators.
