Summary

THE INVOLVED VEHICLES DO NOT CONFORM TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS", IN THAT SOME DUAL COMPARTMENT AIR RESERVOIRS WERE INSTALLED WITHOUT A DRAIN VALVE IN BOTH COMPARTMENTS. THE OMISSION OF THE DRAIN VALVE COULD CAUSE: 1" THE TANK TO FILL UP WITH WATER DUE TO CONDENSATION, 2" REDUCED AIR VOLUME, 3" CONTAMINATION OF THE AIR SYSTEM WITH WATER, CAUSING MALFUNCTION OF THE RELEASE VALVES, CHECK VALVES, ETC., AND INCREASING THE POSSIBILITY OF AIR SYSTEM COMPONENT FREEZE-UP IN COLD CLIMATES. THESE CONDITIONS COULD RESULT IN MOMENTARY LOSS OF BRAKING ACTION.
