The results of interaction of cast iron and composite brake shoes against wheel treads on dynamometer during carry out certificate tests of brake shoes are examined. It has been established that cast iron brake shoes are more aggressive against the wheel running surface. They have inclination to emerge of transverse cracks in tread. On the contrary the composite brake shoes and sintered materials too did not cause the formation of the thermal cracks in the wheel tread owing to more low temperatures rise in friction contact layers. Like this use of composite and sintered material brake shoes in field service on Railway Rolling Stock is more preferable.
