Strick Trailers, LLC
The problem
AN INCORRECT RATIO RELAY VALVE WAS INSTALLED IN THE BRAKE SYSTEM AND THE PRESSURE PROTECTION VALVE WAS INSTALLED INCORRECTLY.
Risk
INCORRECT INSTALLATION OF THE VALVES WOULD REDUCE THE AVAILABLE RESERVOIR CAPACITY BY ONE HALF, RESULTING IN LOSS OF NORMAL BRAKING FUNCTION AND COULD CAUSE APPLICATION OF THE SPRING BRAKES, WHICH COULD EFFECT THE OPERATION OF THE TRUCK AND RESULT IN AN ACCIDENT.
What owners should do
REPLACE THE BRAKE RELAY VALVE AND RE-ORIENT THE PRESSURE PROTECTION VALVE.
