<p>An assembly (1) of disc brake caliper (2) having a caliper body (12), a disc brake pad (3), and at least one pad retracting device (4) from a braking disc (5) suitable to retract said pad from one of opposite braking surfaces (6, 7) of said braking disc (5); said pad (2) comprising: - friction material (8) suitable to abut against said braking surface (6 or 7) and to exert a braking action; - a support plate (9) suitable to support said friction material (8) and to receive a thrust from at least one thrust device (10) received in said disc brake caliper body (12); said support plate (9) comprising a plate portion (14) defining a plate opening (13) facing said caliper body (12) and which allows accessing a plate seat (15) at least partially obtained in said support plate (9); wherein said pad retracting device (4) is separated from each thrust device (10); said pad retracting device (4) comprises: - at least one guide pin (11) integrally secured to said caliper body (12); - said guide pin (11) projects in a cantilevered manner from said caliper body (12) and it is received in said plate opening (13), and with its pin end portion (16) in said plate seat (15); and wherein said pad retracting device (4) comprises a carriage (17) arranged astride of said plate portion (14), having a first carriage portion (18) facing the caliper body (12) with respect to said plate portion (14), and a second carriage portion (19) facing said friction material (8) and/or said braking disc (5); said pad retracting device (4) further comprises a carriage guide (20) coupled with a predetermined interference between said carriage (17) and said guide pin (11 ), allowing said carriage (17) sliding with respect to said guide pin (11) when the action determined by said predetermined interference is exceeded; said pad retracting device (4) further comprises an elastic device (21) arranged between said second carriage portion (19) and said plate portion (14); said elastic device (21) having an elastic characteristic capable of an elastic action of a lesser extent than said action determined by said predetermined interference determined by said carriage guide (20) with said guide pin (11), so as to force said support plate (9) to move away from said second carriage portion (19), which remains integral to said guide pin (11), and thus from said braking disc (5) by a predetermined extent.</p> |
