A method of operating an elevator system is provided and includes recognizing that brakes of an elevator car fail to drop upon brake power being removed, temporarily hovering the elevator car in place to allow the elevator car to be emptied, controllably moving the elevator car in a direction of imbalance, which is defined in terms of relative weights of the elevator car and a counter-weight and torque applied to the elevator car for driving the elevator car upwardly or downwardly, to either a top or a bottom of a hoistway and confirming that the brakes are failing to drop or provide sufficient holding torque.
