A hydraulic control system 1 for a vehicle is provided. The hydraulic control system 1 includes a controller 2 and a closed hydraulic circuit. The hydraulic circuit comprises: a pump 3 having an inlet and an outlet; valve means 40, 50, 60 operatively connected to the controller 2 and fluidly connected to the inlet and outlet of the pump 3; an actuator 4, 5, 6 fluidly connected to the valve means 40, 50, 60 for selectively receiving pressurised fluid therefrom; and a bleed assembly 8 fluidly connected between the valve means 40, 50, 60 and the inlet of the pump 3. The bleed assembly 8 includes: an inlet port 80 for fluidly connecting the inlet of the pump 3 to a source of fluid FS; an outlet port 82 for fluidly connecting the valve means 40, 50, 60 to a discharge reservoir DR; and a shutoff means 7 between the inlet port 80 and the outlet port 82 for selectively opening and closing fluid communication therebetween.
