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).

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.
