ABSTRACT:
A park brake apparatus for a vehicle electric brake comprises an electric motor having a rotational output shaft coupled to a brake mechanism. Rotational movement of the electric motor in a first direction causes application of brake force in the brake mechanism and rotational movement of the electric motor in a second direction opposite the first direction causes release of brake force in the brake mechanism. An armature for the electric motor includes a plurality of radially extending armature arms. A solenoid has a plunger movable between extended and retracted positions. In the retracted position, the plunger is free of the radially extending armature arms and the armature spins free of the plunger. In the extended position, the plunger engages the radially extending armature arms, locking the armature in place and maintaining a park brake state.
