The problem
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH BRAKE VALVES MANUFACTURED BY HONEYWELL BENDIX. THE ORIENTATION AND LOCATION OF THE BRAKE VALVE IS SUCH THAT WATER CAN GET INTO THE VALVE THROUGH A VENT IN THE VALVE. THE WATER WILL CONTAMINATE THE AIR SYSTEM AND COULD FREEZE THE BRAKE VALVE.
Risk
IF FROZEN, THE OPERATOR WILL NOT BE ABLE TO MODULATE THE BRAKE FORCES WITH THE BRAKE PEDAL.
What owners should do
DEALERS WILL INSPECT THE AIR BRAKE SYSTEM AND MODIFICATIONS WILL BE MADE TO THE BRAKE VALVE.
