BRAKE CALIPER

The present invention relates to a brake caliper (1, 1') for a disc brake (10) comprising a caliper body (2), a brake pad (3) and at least one retraction device (4) of the brake pad from a braking disc (5), said device (4) being configured to retract said brake pad (3) from at least one of opposite braking surfaces (6, 7) delimited by the braking disc (5). The brake pad (3) comprises a friction material (8) delimiting a pad plane (11) adapted to lean against the braking surface (6, 7) to exert a braking action on the braking disc (5), said brake pad (3) being adapted to receive a thrust along an axial direction (X-X) by at least one thrust device (15) hosted in the caliper body (2). The caliper body (2) delimits a first pad abutment surface (12), inclined in a non-orthogonal direction with respect to the pad plane (11) and with respect to said axial direction (X-X), to delimit a tapered space (13) with the braking surface (6, 7) of the braking disc (5), the first pad abutment surface (12) being oriented so that, during the braking action, said surface (12) guides the brake pad (3) wedging in the tapered space (13). Furthermore, the brake pad (3) delimits a retraction surface (14), inclined in a non-orthogonal direction with respect to the pad plane (11) and oriented so that, during the retraction action, the brake pad (3) is guided partially outside of the tapered space (13). The retraction device (4) of the brake pad (3) comprises a working portion (16, 17), movable in a transverse direction (Y-Y), either incident or substantially orthogonal with respect to the axial direction (X-X), said portion (16, 17) being pressed in abutment of the retraction surface (14), slidably along the latter, to retract the brake pad (3).
