A floating caliper partial lining disc brake is described in which a metal bearing sleeve is arranged between the bolt and the bore of the brake caliper, so that a metal-to-metal contact exists on the slideway. Arranged on the one axial end section of the metal bearing sleeve, outside the bore of the brake caliper, is an elastomeric bush which at its one axial end is fixed on the brake caliper and which is provided on its inside with a plurality of spaced annular ribs. The annular ribs of the elastomeric bush bear in a sealing fashion on the outer surface serving as slide surface, so that, in the event of a relative movement between the bearing sleeve and the elastomeric bush, a cleaning action is produced, the chamber-like cavities lying between the ribs serving to receive dirt or other impurities. <IMAGE>
