Compo c/bb/k brake block is a rigid moulded friction material, Grey, Black in colour, Having a random fibre asbestos base and containing metallic particles. It is produced only in the form of integrally moulded, Brake blocks to a back plate. This material was originally developed to have the potential to withstand the heavy braking demands of electric multiple unit operating suburban, Emu stock passenger services. Its use has since been extended to a variety of duties from low speed shunting locomotives to high speed passenger trains. C/bb/k has a higher and more stable friction ratio than the conventional cast iron block which resulting in, It replaces lower application forces and permitting the employment of smaller cylinders. This solution is a conformable block designed to eliminate thermal cracking of tyres, Which had hitherto been a barrier to the widespread use of composition blocks. C/bb/k block has several fold advantages in life over cast iron blocks and thus significantly lengthens service periods. It is particularly beneficial in those situations where hot cast iron dust would present a safety hazard. Spark, Free blocks are essential in oil refineries, Chemical works and ordinance factories. The composition block has much to present as a component of the braking of minimising braking, Passenger rail shocks by its smoother action and permitting higher load/tare factor. Indian railways have been successfully using composition brake blocks for emu rakes for over even in, Three decades monsoon conditions.
