Claim:
1. A simulated electro-hydraulic (EH) braking system for a work machine, comprising: a brake control valve in fluid communication with a pressurized fluid source and operatively connected to a brake control to move between a normally closed position and an open position in response to a displacement of the brake control to produce a commanded brake pressure at a brake valve outlet that corresponds to the displacement of the brake control; a brake control sensor operatively coupled to the brake control to sense the displacement of the brake control and output a brake control sensor signal that corresponds to the displacement of the brake control; a pressure reducing valve having an open position and a maximum bleed position, a pressure reducing valve inlet in fluid communication with the brake valve outlet, a first pressure reducing valve outlet in fluid communication with a brake cylinder, and a second pressure reducing valve outlet in fluid communication with a low-pressure reservoir, wherein a pressure reducing valve output pressure at the second pressure reducing valve outlet increases from zero at the normally open position to a maximum bleed pressure at the maximum bleed position; a controller operatively connected to the brake control sensor and the pressure reducing valve, wherein:
