Abstract

A brake device for a drivable part, in particular for use for a vehicle flap, in particular in an automobile, includes a drivable load device (11) which can be radially brought into contact with a disc (90) of the drivable part, with a first holding position and a second release position. At least one brake element rests against the periphery (92) of the disc (90) in a frictional manner in the holding position and secures the disc (90) from rotating using a specifiable force. In the release position, the at least one brake element is arranged at a distance from the periphery of the disc (90) and allows a free run of the disc (90), and the load device (11) can be adjusted between the holding position and the release position, preferably by a motor (12). A brake device or a rotating drive with which a drivable part of the drive is secured against a displacement on the basis of the mass of the component to be displaced even when the motor is not being provided with power or is deactivated is achieved in that the first holding position and the second release position are each designed as a metastable holding position.
