Abstract
A hydraulic vehicle brake has a piston which acts upon a friction element and is displaceable by a rotationally drivable spindle/nut arrangement into an actuating position. A spindle of the spindle/nut arrangement is secured against rotation and movable by the spindle nut either into abutment against the piston or away from the piston. The spindle nut comprises a first part, which at least close to one end thereof is configured for screw-type engagement with the spindle, and a second part, configured for rotationally driving the first part and connected to the first part by a rotationally fixed connection. The first part at an other end thereof is provided with a support surface for the rotatable, axial mounting of the spindle/nut arrangement and the second part at the other end extends into the first part.
