The problem
VEHICLE DESCRIPTION: S -TRUCKS EQUIPPED WITH 2 WHEEL DRIVE. THESE VEHICLES MAY HAVE HAD THE RIGHT-HAND ANTILOCK BRAKE SYSTEM (ABS) MODULE FEED PIPE AND/OR BRAKE CROSSOVER PIPE TUBE NUTS TIGHTENED WITHOUT SEATING THE PIPE-FLARED-ENDS ENOUGH TO WITHSTAND NORMAL ASSEMBLY AND VEHICLE INPUTS WITHOUT PARTIALLY UNSEATING. THIS DOES NOT COMPLY WITH REQUIREMENTS OF FMVSS NO. 105, "HYDRAULIC SERVICE BRAKE NORMAL, EMERGENCY, AND PARK BRAKING PERFORMANCE."
The risk
IF THIS OCCURRED, THE SEATING SEAL COULD BE BROKEN DURING VEHICLE ASSEMBLY, OR FROM EARLY ROAD INPUTS OR BRAKE FLUID CYCLING, AND A LEAK COULD OCCUR INCREASING THE BRAKE STOPPING DISTANCE.
The fix
DEALERS WILL INSPECT THE BRAKE PIPE UNION FOR SIGNS OF BRAKE FLUID, AND IF NECESSARY, INSTALL A NEW BRAKE PIPE UNION.
