Abstract
A brake device for an electrically operatable axle drivetrain of a motor vehicle includes a hydraulic disengaging system comprising a central disengaging element which actuates a friction device such that the friction device operates in a braking or non-braking state. The central disengaging element has a central disengaging element housing comprising a central disengaging element piston chamber in which a central disengaging element piston is received in an axially movable manner by means of a hydraulic liquid. The central disengaging element has at least one central disengaging element piston seal which seals off the central disengaging element piston from the central disengaging element piston chamber, and the central disengaging element and the friction device are received in a brake housing, the brake housing including a first pot-shaped housing part and a second lid-shaped housing part which at least partly covers the first pot-shaped housing part.
