Abstract
An electronically controlled parking brake system for a vehicle including a housing connected with the vehicle chassis, a movable member adapted for connection with the parking brake cable of the vehicle, a main spring biasing the movable member toward a brake-applied position relative to the housing, an electric motor operable to displace the movable member toward a brake-released position relative to the housing, a retaining device normally retaining the movable member in the brake-released position, and a release device for releasing the retaining device, whereby the movable member is released for displacement by the main spring toward the brake-applied position. Preferably, the retaining device includes a helical clutch spring mounted concentrically on a rotatable drive screw that drives the movable member in the brake-released direction, and the release device includes a solenoid for releasing the clutch spring.
