Abstract
A power closure actuator for powering a movable closure includes a shaft situated between an electric motor and an output member. A brake device along the shaft is configured for actuation via an electric brake actuator to apply braking. An active brake clamp is movable by the electric brake actuator. An axially floating rotor is rotatable with the shaft and has a first axial side facing the active brake clamp a second axial side providing a second braking surface. A passive backing brake clamp is positioned adjacent the second braking surface. The axially floating rotor is biased away from the passive backing brake clamp by a first biasing member. Deflection of the first biasing member coupled with axial movement of the active brake clamp and the axially floating rotor enables braking by pinching action of the axially floating rotor between the active brake clamp and the passive backing brake clamp.
