Abstract
A pad for disc brakes for railway vehicles includes a base plate, a plurality of friction elements fixed to the base plate, and a plurality of spacers, each of which is mounted between the base plate and a respective friction element. At least one fixing hole is obtained in each one of the spacers, which is engaged by a respective rivet to lock the friction element to the base plate. Each one of the spacers includes a plurality of metal plaques, each having a fixing hole obtained in the plaque. The metal plaques are stacked on top of one another so that the respective fixing holes coincide.
