<p>The invention relates to a disk brake comprising a caliper (10) sliding on a fixed support (12) by means of at least one axial small column (14), the caliper (10) comprising actuation means (28) susceptible of biasing at least one friction element (22, 24) being anchored and sliding in the fixed support (12), against a rotating disk (26), locking means (30) for the caliper (10) rotating about the small axial column (14) on the fixed support (12), formed of an axial pin comprising a rod (32; 70, 72) of which one part (32) slides in a bore (34) provided in the fixed support (12) or the caliper (10), and a foot (36) forming a planar stop surface (38) which is perpendicular to the axis of the axial pin and intended to bear against a planar portion (40) of the caliper (10) or of the fixed support (12), the foot (36) of the axial pin cooperating with a locking member (44; 74, 80) traversing with clearance a mounting opening (46) provided in the caliper (10) or the fixed support (12) in order to provide for an axial centering of the pin when assembling the brake. According to the invention, a support member (50, 76, 150) is arranged at the vicinity of the mounting orifice (46) in order to secure the axial pin against rotation during the brake assembly, the axial pin being secured against radial translation by the bore (34).</p> |
