The short version

PACCAR INCORPORATED reported a problem with the service brakes, air. Here is what owners need to know.

WHAT

CERTAIN TRUCKS FAIL TO COMPLY WITH THE BRAKE TIMING REGULATORY REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS." THE BRAKE VALVE WAS MOVED TO THE OPPOSITE RAIL, INCREASING THE LENGTH OF THE AIR LINE, WHICH IN TURN INCREASED THE WHEELBASE REQUIRING A DUAL RELAY VALVE SYSTEM.

WHY IT MATTERS

IF STOPPING DISTANCE WAS LIMITED, A VEHICLE CRASH COULD RESULT.

WHAT TO DO

DEALERS WILL CONVERT THE SINGLE RELAY VALVE TO A DUAL RELAY VALVE SYSTEM FREE OF CHARGE.
