Exhaust Brake solenoid failure.
Exhaust brake would not release.
Had to manually (with a wrench) break the air line to exhaust the air from the cylinder and then drive without the exhaust brake (not recomended, but I was in the middle of nowhere on I77 in WVA). The brakes heated up enough to smell pretty strongh. Cunnins shop replaced the defective part (solenoid) under Monaco warranty but I was deadlined a week waiting for it. (I now carry a spare) Note: the solenoid manufacturer is ISO certified and has few failures.
