Systems and methods for simulating electro-hydraulic (EH) braking of a work machine using a combination of hydraulic braking and engine braking may include determining a commanded brake pressure requested by an operator, determining an available engine braking force, and comparing the available engine braking force to a maximum available bleed pressure that is available to reduce a hydraulic braking force. An engine braking output and a pressure reducing valve output pressure may be determined based on the available engine braking force and the maximum available bleed pressure. A pressure reducing valve may be actuated so that the hydraulic braking force is equal to the commanded brake pressure minus the pressure reducing valve output pressure, and a transmission may be actuated so that the engine applies an engine braking force equivalent to the engine braking output to brake the work machine.
