    Abstract: The invention provides an electric brake system and method. The electric brake system includes an electric motor having a portion moveable along a path between a plurality of positions for moving a brake pad and applying a selectable amount of braking force on a brake rotor. One of the plurality of positions is a minimal contact position. The minimal contact position is operable to change among the plurality of positions over time. The electric brake system also includes an electric controller for controlling the electric motor to move the portion along the path between the minimal contact position and at least one other of the plurality of positions for moving the brake pad and for selecting the amount of braking force. The electric brake system also includes at least one sensor for sensing at least one of motor current, motor acceleration, controller voltage, motor speed, motor voltage, and motor temperature, and communicating a sensed condition to the controller.
