1. Disc brake caliper comprising:

  • a caliper body placed astride the disc of a disc brake, fitted with a pair of half-bodies connected to each other by means of a first and a second end bridge suitable to delimit a central aperture of the caliper body, and by means of a first and a second connection bridge placed astride the disc of the brake disc at said central aperture,said caliper body housing brake pads supported by suspension pins for pads positioned in an axial direction of the caliper body, said pads having a first side facing the disc of the disc brake, connected to an opposite second side by means of a corner facing said central aperture,said caliper further comprising a first and a second cross-shaped leaf spring to influence the pads in said axial direction,wherein said first/second spring is suitable to act between the pads and between the first/second connection bridge and the first/second end bridge of the half-bodies, said first/second leaf spring comprising a bow-shaped longitudinal beam having a shaped first end suitable to be removably constrained to the first/second connection bridge and an opposite second shaped end suitable to be removably constrained to the first/second end bridge,wherein each of said first and second leaf springs comprises;

    a cross beam connected to the longitudinal beam at a central base portion of the spring, to influence the pads at suspension portions of the pads towards the pins,said cross beam including wings which project from the central base portion of the spring in said axial direction,each of said wings having a surface facing the disc of the disc brake suitable to rest on the corner of the respective pad,each of said wings comprising first means for influencing the pads to influence the second side of the pad keeping it away from an inner wall of the half-bodies, each of said wings comprising second means for influencing the pads to influence the first side of the pad away from the disc in said axial direction and to influence said pad in suspension on the pins in a direction orthogonal to said axial direction away from said first and second connection bridge.
