It consists of two independent brake systems that use a single set of brake controls. Each circuit is supplied by its own compressed air tank which is protected by a check valve.

Their function is to build up, maintain and control air pressure in the reservoirs. This is so that pressure is held constant between the minimum and maxi- mum range established for air brake operation.
