Claim:
1. Vehicle brake, having a housing and a brake piston arranged therein, which brake piston acts upon a friction element and is displaceable by means of a rotationally drivable spindle/nut arrangement arranged coaxially with a central axis of the brake piston into an actuating position, in which the brake piston presses the friction element against a rotor of the vehicle brake, the spindle/nut arrangement comprising a spindle and a spindle nut, wherein the spindle is secured against rotation and is moved by means of a rotation of the spindle nut in a translatory manner along the central axis either into abutment against the brake piston or away from the brake piston in dependence upon a direction of rotation of the spindle nut, wherein the spindle nut comprises a one-piece first part and a second part, wherein the first part is in the form of a sleeve extending axially from one end to an other end, which at least close to the one end thereof is configured for and in direct threaded engagement with the spindle, and wherein the second part is configured for rotationally driving the first part and is connected to the first part by a rotationally fixed connection, wherein the first part at the other end thereof remote from the one end is provided with a support surface for the rotatable, axial mounting of the spindle/nut arrangement, wherein the second part at the other end extends into the first part, and wherein a recess extends from the support surface into the first part at the other end, which recess form-fittingly receives, in a circumferential direction, the second part of the spindle nut provided with a hollow stud formed complimentary to the recess, wherein the first part, at a surface of the first part facing the spindle, is, at least in sections, unthreaded.
