<p>1. A disk brake including a caliper (18) slidingly mounted by means of two axial columns (14, 16) on a fixed support (10), actuating means (28) being associated with the caliper to urge directly a first friction member (36) against a first face of the disk (12) and by reaction via the sliding caliper a second friction member (38) against the other face of the disk (12), said columns (14, 16) being fixed to the caliper and traversing guiding and sliding bores (20, 22) provided in two circumferentially spaced arms (24, 26) of the fixed support (10), said caliper (18) comprising first force transmitting means (78, 80 ; 14, 16) situated in a plane perpendicular to that of the disk and comprising on the one hand said columns (14, 16) and on the other hand a first portion (70) of the caliper disposed on one side of the disk as well as a second portion (80) of the caliper disposed on the other side of the disk, and said fixed support (10) comprising second force transmitting means situated in a plane parallel to that of the disk and comprising a beam forming portion (92) of the fixed support connecting said circumferentially spaced arms (24, 26) to each other at their basis, characterized in that said second force transmitting means further include a beam forming element (90) which is radially spaced from said portion (92) of the fixed support and which connects the ends of said arms (24, 26) to each other, said element participating in said transmission of a portion of the brake forces from one of the arms to the other of the arms irrespective of the sense of rotation of the disk, and permitting radial removal of the friction members (36, 38) through an opening in the caliper (18).</p> |
