Abstract
A pad for disc brakes for railway vehicles is provided. The pad includes a base plate and friction elements fixed to the plate and arranged in at least two arcuate rows. Each row has friction elements with one same friction surface and a total friction surface ranging from 40% to 80% of the total friction surface of the friction elements of a neighboring external row. Each friction element of at least one neighboring internal row has a friction surface that is less than the friction surface of each friction element of the neighboring external row. The friction elements of each row are arranged on the base plate to act on a surface portion of a brake disc, which partially overlaps surface portions of the disc on which friction elements of a neighboring external row and friction elements of a neighboring internal row act.
