COMPOSITION BRAKE SHOES ON BRAZILIAN ELECTRIC STOCK

Extensive trials on the Central Railway of Brazil have led to the adoption of Cobreq non-metallic brake shoes for multiple-units and ore wagons. Compared with cast-iron shoes the distance run between reblocking has increased sevenfold and the life of the tire between turning has been more than doubled. The tests extended over some three years. Cast-iron shoes weighed 29 lb and had an average life of 7,000 km. Tire profiles show almost complete absence of grooves forming on the tread, a disadvantage frequently associated with non-metallic brake shoes.
