Abstract
A brake system is provided for a trailer vehicle having a plurality of axles, each of which has a wheel end on a respective side of the vehicle, the brake system including first and second pneumatic circuits for supplying air pressure to brake devices at the wheel ends. The system includes a spring brake modulator valve arrangement adapted to control pressure to spring brakes on the vehicle, which modulator valve arrangement receives an input from at least one of the pneumatic circuits and a control pressure from the trailer brake module. Flow of air to the brakes is controllable either by the trailer brake module or by the spring brake modulator valve arrangement to provide redundancy.
