Electromagnetic spring-loaded brake (1) with a rotatable about an axis of rotation d brake disk arrangement (4, 6, 8, 10, 12), which is disposed coaxially between a brake flange arrangement (14, 16) and an armature ring arrangement (14, 22, 24), which, in order to create a braking effect by the brake disk arrangement (14, 16, 18) in an axial direction via brake springs (50) and for the braking effect in the opposite axial direction by means of an electromagnetic coil arrangement (36, 34) can be applied, characterized in that the prestress of a brake shoe return spring (50) via a corresponding setting means (52, 55) is variable.
