Abstract

An automatic adjustment arrangement for disk brakes has a flanged threaded nut and a threaded spindle threadedly coupled thereto arranged between the brake piston and the hand brake piston. The flange of the threaded nut is axially form-locked and radially displaceable relative to the brake piston. The threaded spindle is rotatably supported in a rolling bearing which is radially displaceable. The hand brake piston and threaded spindle are frictionally coupled. The extension of the adjustment member is produced by rotation of the threaded spindle. To avoid malfunctions, an automatic centering of the entire adjustment element relative to the brake piston as well as relative to the housing is provided. Manufacturing and assembly errors are thereby compensated for. The positions of the threaded spindle and threaded nut can be interchanged.
