A pad assembly adapted to be mounted in a caliper body for a disc brake has a pad-housing pocket. The disc brake defines an axial direction, either coinciding or parallel with the direction of the rotation axis of the brake disc associable with the caliper body, a radial direction (R-R), orthogonal to the axial direction, and a tangential (T-T) or circumferential (T-T) direction, orthogonal both to the axial direction and to the radial direction (R-R). The pad-housing pocket has at least one pocket wall to form a tangential abutment for a brake pad associable with the caliper body. The pad assembly has a brake pad having a support plate, adapted to form a support for at least one associable friction material, where the support plate has a main extension along the radial (R-R) and tangential (T-T) directions. The support plate has a predefined bulk along the tangential direction (T-T), or tangential bulk, such that the support plate is adapted to be accommodated with a predetermined tangential play in the pad-housing pocket. The pad also has at least one elastic element.
