A sliding key (10), interposed between the end (5) of an arm (4) of the fixed support (1) and the adjacent profiled end (60, 70) of the sliding caliper (8), is immobilized axially by a component (15), advantageously elastic, having end portions (16) cooperating in engagement with the axially opposed ends of the key (10) and joined by an intermediate portion (20) of undulating profile defining with the adjacent outside zone of the end (5) of the arm (4) a channel (24) for a wire conductor (25) to pass through, for connection to a pad wear detector, brought to the side of the brake opposite this pad.
