a clearance 34 a 34 is provided between supporting surfaces 23 and 24 and the neighboring surfaces 27 and 28 of brake caliper 1 guide pins 9 and 10 abut against cylindrical cups 25 and 26 in this arrangement the distance between cup 25 and cup 26 is slightly larger than the distance between bores 11 and 13 and bores 12 and 14 so that rubber rings 15 are slightly compressed resulting in a clearance 34 b 34 between guide pins 9 and 10 and bores 11 12 13 and 14 for brake actuation brake caliper 1 has a wheel brake cylinder 29 with an actuating piston 30 when the brake is applied brake actuating piston 30 is first displaced moving brake shoe 4 into engagement with brake disc 2 as soon as brake shoe 4 is in abutment with brake disc 2 the reaction force effective at wheel brake cylinder 29 displaces brake caliper 1 in the opposite direction until the clearance l between brake disc 2 and brake shoe 4 39 is overcome and brake shoe 4 39 is in abutment with brake disc 2 at the same time rubber rings 19 are compressed and urged into bores 13 and 14 so that stop heads 17 and 18 abut against brake caliper 1 if brake disc 2 is rotating in the direction indicated by the arrow the circumferential force generated at brake shoes 4 and 4 39 as a result of the frictional engagement is transferred to brake caliper 1 via the projections 5 and 7 which abut against surface 27 under the action of the circumferential force brake caliper 1 is displaced in the.
