NHTSA Recall 85V171000
Filed by Blue Bird Body Company. Component: Service Brakes, Air. Reported 1985-12-26. An estimated 11 vehicles are affected. Recall repairs are free at any authorized dealer.
Defect
FMVSS 121 REQUIRES THAT THE AIR OPERATED OIL LINE TO THE WET AIR PRESSURE TANK CONTAIN AN AUTOMATIC HIGH PRESSURE VALVE TO PROTECT THE BRAKE AIR LINES. THIS PRESSURE VALVE WAS OMITTED. CONSEQUENCE OF DEFECT: THE OMISSION OF THE PROTECTION PRESSURE VALVE COULD ALLOW THE AIR LINE PRESSURE TO INCREASE TO THE POINT THAT IT WOULD DAMAGE THE AIR LINES AND WOULD RESULT IN DRAINING AIR PRESSURE FROM THE BRAKE SYSTEM CAUSING LOSS OF BRAKES WHICH COULD LEAD TO AN ACCIDENT.
What the manufacturer will do
ADD PRESSURE PROTECTION VALVE TO THE TEE IN THE AIR ACCESSORY LINE.
