1. An assembly comprising:
at least two pads having a support plate and a friction material coating, each of said at least two pads being adapted to be accommodated in a pocket of a caliper so that each of said at least two pads is positionable on a side of a brake disc of a disc brake facing opposite braking surfaces;
said brake disc being a rotor configured to rotate about a disc rotation axis defining an axial direction (A-A), parallel to said disc rotation axis, a radial direction (R-R), orthogonal to said disc rotation axis, and a circumferential direction (C-C) orthogonal to said axial (A-A) and radial (R-R) directions and a tangential direction (T-T) orthogonal to the radial (R-R) and circumferential (C-C) directions at their point of intersection;
at least one spring, arranged straddling the brake disc,
wherein said at least one spring applies an elastic bias on the at least two pads so as to elastically bias the at least two pads away from the brake disc;
wherein said at least one spring is configured to be directly connected only to the at least two pads;
said support plate comprising at least one plate coupling portion,
wherein, in a section of said at least one plate coupling portion on a plane containing the axial direction (A-A) and the radial direction (R-R), said at least one plate coupling portion comprises:
an inner lower edge, configured to face the brake disc in a radially inward direction or towards the disc rotation axis;
an inner upper edge, configured to face the brake disc in a radially outward direction or opposite to the disc rotation axis;
said inner upper edge continues on an upper surface directed according to the axial direction (A-A) parallel to said disc rotation axis, forming an upper spring-coupling plate portion edge;
and wherein said at least one spring is always in contact exclusively with:
said inner lower edge, and
said upper spring-coupling plate portion edge.
