Abstract

A brake system for a trailer has first and second pneumatic circuits for supplying air pressure to the wheel ends on the trailer. The air pressure to brake devices at the wheel ends is controllable via a first brake ECU. First and second pressure control valves control pressure from the pneumatic circuits to the respective wheel ends. The system further has a second ECU adapted to electrically control the actuation of the pressure control valves.
