Factors influencing exploitation properties of brake shoes on rolling stock

This paper presents test results of examining friction and wear properties of brake shoes made of phosphorus gray castings. Brake shoes with different content of phosphorus and hardness levels have been analyzed, and their wear in laboratory conditions of dry rub down in contact with rotating discs of various hardness has been tested. If has been established that brake shoe wear resistance depends much more on chemical compositions and distribution of structural constituent parts then on hardness values of the wheel - disc.
