1. A centering mechanism comprising:
a brake piston of a disk brake of a motor vehicle; and
a nut/spindle module comprising a spindle that projects into a recess of the brake piston and a nut that is screwed onto the spindle;
wherein the nut has a nut support surface and the brake piston has a brake support surface that lies opposite the nut support surface;
wherein in the case of a vertical arrangement, with the brake piston below the spindle and the nut, a force equilibrium is avoided when the nut/spindle module has been moved out of the vertical position; and
wherein the nut/spindle module has a center of gravity and in the case of the vertical arrangement, the center of gravity of the nut/spindle module moved out of the vertical position is distanced from a contact plane of the nut and brake support surfaces in an amount less than half the diameter of the contact plane of the nut and brake support surfaces.
