The present application provides a hydrostatic radial plunger unit of a cam lobe structure, comprising: a non-rotating fixed housing, the fixed housing comprising a through hole defining a rotational axis of the hydrostatic radial plunger unit; a rotary housing rotatably mounted to the fixed housing in an axial overlap region; the parking brake mechanism comprises at least two brake discs which are adjacently arranged in the overlapping area; the invention relates to a brake device for a motor vehicle, comprising a fixed housing, an end cap, which preloads a disc spring against a disc-shaped brake piston in order to generate an axial spring force, both the disc spring and the brake piston being located in a rear end portion of the fixed housing, the spring force being transmittable through the brake piston to at least one brake pin arranged in an axial bore in the fixed housing, when the brake piston opposite to the disc spring is not driven to move towards the end cover, the brake discs are pressed against e
