GRUMMAN FLXIBLE CORP.
The problem
THE INVOLVED VEHICLES DO NOT CONFORM TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS". THE REQUIRED BRAKE RELEASE TIME OF 0.55 SECONDS MAY NOT BE ATTAINABLE DUE TO DISCONNECTION OF THE ROCKWELL SKID CONTROL VALVE WHICH HAD PERFORMED THE RELAY VALVE AND QUICK RELEASE FUNCTIONS.
What owners should do
DEALER WILL INSPECT AND, IF NECESSARY, INSTALL THE COMPONENTS NEEDED TO BRING THE BRAKE RELEASE TIME INTO COMPLIANCE WITH THE STANDARD.
