1. A disc brake including a caliper (14) forming a frame at least partially surrounding a fixed support and slidingly mounted by means of at least one axial column (16, 18) on the fixed support (10) wherein two friction elements (32, 34) are anchored and slidingly received, which friction elements are adapted to frictionally engage the opposite faces of a rotating disc (12) upon actuation of actuating means comprised of at least one brake motor (24, 24', 24'') acting directly upon the one (32) of the friction elements and acting upon the other (34) friction element by reaction via the sliding caliper (14), the column (16, 18) extending within bores (46) provided in opposed relation within the fixed support (10) and the caliper (14), characterized in that the caliper (14) comprises at least one axial reinforcing member (62, 62') disposed radially beyond the periphery of the disc (12) and connecting a first portion (51) of the caliper disposed at the side of the brake motor (24) and a second portion (52) of the caliper to each other in axial force-transmitting relationship, the second portion of the caliper being adapted to bias said other friction element (34) in a first zone (54) being axially more remote from the axis of the disc towards the exterior than the pressure center (A) of the brake motor, said other friction element (34) being biased in a similar manner by the second portion (52) of the caliper in at least a second zone (56) being radially less remote towards the exterior than the pressure center (A) of the brake motor the reinforcing member preventing bending of said first zone (54) during brake application. |
