Service Brakes, Air:supply:hoses, Lines/piping, And Fittings
Reported Jan 22, 1979 · PULLMAN, INCORPORATED
Summary
THE REAR EMERGENCY GLAD HAND WAS IMPROPERLY CONNECTED DIRECTLY TO THE REAR AIR TANK RATHER THAN TO THE EMERGENCY PORT OF THE TASK VALVE. CONSEQUENTLY, IF THE AIR SUPPLY TO THE LEAD TRAILER BECAME DISCONNECTED, THE EMERGENCY BRAKES WOULD BE APPLIED BUT THE REAR TRAILER"S WOULD NOT. A HEAVY BRAKE APPLICATION WOULD CAUSE THE REAR TRAILER TO PUSH THE LEAD TRAILER FORWARD, INCREASING THE VEHICLE BRAKING DISTANCE, AND CREATING THE POTENTIAL FOR A JACK KNIFE.
Consequence
