A pad-and-spring assembly for a brake caliper for a disc brake, wherein an axial direction (X-X) either coinciding with or parallel to the rotation axis of a brake disc of said disc brake, a radial direction (R-R) orthogonal to the axial direction (X-X), and a tangential direction (T-T) orthogonal to both the axial direction (X-X) and the radial direction (R-R) are defined, wherein said radial direction (R-R) defines a radially inward direction, directed towards the rotation axis of the brake disc, and a radially outward direction, opposite to the radial inward direction; said assembly comprises: - at least one brake pad comprising friction material and a supporting plate which supports said friction material; - at least one elastic device, adapted to apply an elastic biasing action directed in axial direction (X-X) to said brake pad to move it away from the brake disc when the braking action ceases; wherein: - said supporting plate comprises a surface facing the disc, intimately associated with said friction material, and a plate back, axially opposite to said disc facing surface and adapted to face thrust means of the brake caliper which can be associated with said assembly; - said friction material comprises a radially inner edge, adapted to face the rotation axis of the brake disc, and a radially outer edge, radially opposite to said radially inner edge; - said radially outer edge of the friction material defines the outer radial dimension level of the friction material with its tangential extension on said surface facing the disc of the supporting plate; - said disc facing surface of the supporting plate comprises at least one free surface, which is free from the contact with the friction material and adapted to face a braking surface of the brake disc which can be associated with said assembly, wherein said free portion is located radially inside with respect to said at least one tangential extension of the radially outer edge of the friction material; - said free surface of the disc facing surface of the supporting plate of brake pad comprises at least one through opening edge which at least partially delimits a through opening in axial direction (X-X) through said supporting plate of brake pad; and wherein said at least one elastic device has a body comprising: - at least one connecting portion (21, 21'), adapted to connect to the body of the brake caliper which can be associated with said assembly; characterised by - at least one supporting portion, which rests against said through opening edge of the free surface of the supporting plate, axially crossing said through opening of the supporting plate to apply an elastic biasing action directly in axial direction (X-X) to said through opening edge of said through opening. - at least one brake pad comprising friction material and a supporting plate which supports said friction material; - at least one elastic device, adapted to apply an elastic biasing action directed in axial direction (X-X) to said brake pad to move it away from the brake disc when the braking action ceases; - said supporting plate comprises a surface facing the disc, intimately associated with said friction material, and a plate back, axially opposite to said disc facing surface and adapted to face thrust means of the brake caliper which can be associated with said assembly; - said friction material comprises a radially inner edge, adapted to face the rotation axis of the brake disc, and a radially outer edge, radially opposite to said radially inner edge; - said radially outer edge of the friction material defines the outer radial dimension level of the friction material with its tangential extension on said surface facing the disc of the supporting plate; - said disc facing surface of the supporting plate comprises at least one free surface, which is free from the contact with the friction material and adapted to face a braking surface of the brake disc which can be associated with said assembly, wherein said free portion is located radially inside with respect to said at least one tangential extension of the radially outer edge of the friction material; - said free surface of the disc facing surface of the supporting plate of brake pad comprises at least one through opening edge which at least partially delimits a through opening in axial direction (X-X) through said supporting plate of brake pad; - at least one connecting portion (21, 21'), adapted to connect to the body of the brake caliper which can be associated with said assembly; characterised by - at least one supporting portion, which rests against said through opening edge of the free surface of the supporting plate, axially crossing said through opening of the supporting plate to apply an elastic biasing action directly in axial direction (X-X) to said through opening edge of said through opening.
