An electric parking brake for a vehicle brake system includes a caliper, a piston, a spindle, an adjuster nut, a ring-like member affixed to the piston, and a biasing member. The piston may be disposed within a cavity of the caliper. The spindle is configured to drive the axial movement of the adjuster nut between a retracted position and an extended position via a threaded engagement wherein the adjuster nut is disposed within the piston. The biasing member may be disposed between the ring-like member and the adjuster nut so that, as the adjuster nut moves from an extended position to a retracted position which corresponds to a control signal, the biasing member urges the piston away from the rotor.
