The problem
THE FRONT BRAKE AIR LINES ARE INCORRECTLY ROUTED THROUGH THE PRESSURE PROTECTION VALVE AT THE AUXILIARY WET TANK. THIS RESULTS IN LACK OF AIR PRESSURE TO THE FRONT BRAKES WHEN THE AIR PRESSURE IN THE AUXILIARY WET TANK DROPS BELOW 65 P.S.I., RESULTING IN INOPERABLE FRONT BRAKES.
Risk
WHEN THERE IS NO FRONT BRAKE APPLICATION, STOPPINGDISTANCE INCREASES, AND THERE IS AN INCREASED RISK OF ACCIDENT.
What owners should do
CORRECTLY REROUTE THE BRAKE LINES.
