Abstract
A dual hydraulic booster assembly for a braking system of a tractor or like vehicle has a logic valve operable in a first mode to control the supply of pressure fluid for braking on one side of the vehicle to facilitate steering, and in a second mode of operation to control the supply of fluid pressure for braking on both sides of the vehicle for full vehicle retardation. A pressure amplifier valve may be provided to increase the pressure of the pressure fluid from the logic valve for braking in the second mode of operation. The logic valve and amplifier valve may be incorporated into the booster assembly to provide an integrated unit.
