A magnetorheological fluid brake utilizing a positive displacement fluid pu mp adapted to pump a magnetorheological fluid through a viscosity regulator. Th e viscosity regulator is adapted to controllably vary the viscosity of the magnetorheological fluid, altering the pumping restriction against the fluid pump, resulting in variable resistance to pump shaft rotation relative to the pump housing. An electronic steering system for a work vehicle utilizing the illustrat ed magnetorheological brake as a resistance device to provide tactile feedback as a function of steering shaft rotational position.
