Abstract: A multi-disk brake (1) for a motor vehicle has two multi-disk mechanisms (7, 8) and an actuation device (9) for brake actuation and/or brake release of the multi-disk mechanisms (7, 8), and an electric drive (16) for translational actuation (spreading) of the actuation device, such as, in particular, the ramp unit (9). During a spreading operation, the multi-disk mechanisms (7, 8) are pretensioned in a metered manner by the actuation device and produce a desired frictional engagement, and a correspondingly reversed activation of the actuating mechanism enables a correspondingly metered brake release. By means of the electric drive (16), the action of the multi-disk brake (1) can be metered overall in a particularly precise, sensitive and compensated manner in modern vehicle topology, including all peripheral brake components and systems, including recuperation.
