A vehicle electric parking brake system includes a power bridge. The power bridge is electrically connected to a primary power source and to a secondary power source. The power bridge has a first condition in which the primary power source is active in which the primary source is electrically connected to a parking brake actuator. The power bridge has a second condition in which the primary power source is not active in which the secondary power source is electrically connected to the parking brake. The system is preferably for an autonomous vehicle. A hydraulic braking system may be associated with the electronic parking brake. The parking brake actuators are preferably electromechanical actuators.
