Triad Mack Sales: Service Brakes, Air › Supply › Check Valve
Triad Mack Sales reported this defect to federal regulators on Sep 23, 2002 and put the number of vehicles at risk at 122. The repair is free for as long as the recall stands.
The defect
ON CERTAIN TRAILERS EQUIPPED WITH SPRING BRAKE CONTROL VALVE ASSEMBLIES. THERE IS A RECESSED AREA ON TOP OF THE VALVE IN WHICH A BRASS GUIDE PIN FITS DOWN INSIDE THE BODY OF THE VALVE AND IS HELD IN PLACE BY A STEEL SNAP RING. THE RECESSED AREA ALLOWS ACCUMULATION OF WATER, DIRT, AND/OR CHEMICALS TO BUILD UP BEHIND THE SNAP RING TO THE POINT WHERE IT WILL NO LONGER CONTAIN THE GUIDE PIN RESULTING IN A FAILURE OF THE AIR VALVE.
The risk
FAILURE OF THE VALVE IN AN EMPTY OR LIGHTLY LOADED TRAILER WHILE THE VEHICLE IS IN MOTION COULD RESULT IN A HARD APPLICATION OF THE SPRING BRAKES, POSSIBLY LOCKING UP THE TRAILER WHEELS AND RESULTING IN A VEHICLE CRASH.
The remedy
SEALCO WILL PROVIDE A REPAIR KIT AND INSTALLATION INSTRUCTIONS TO ITS CUSTOMERS FREE OF CHARGE. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT SEALCO AT 602-253-1007 OR TRIAD MACK AT 336-996-6060.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 02V210008.
