Abstract
A method for measurement of contact maintaining control valve current for a hydraulic actuator may comprise sending, by a brake controller, a current signal to an electromechanical valve assembly, receiving, by the brake controller, a pressure feedback signal, increasing, by the brake controller, a value of the current signal, and determining, by the brake controller, a contact current value based upon the pressure feedback signal.
