2000 Triad Mack BIG John & 2000 Triad Mack Dorsey recall: brakes
⚠️ What's wrong
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 fix
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.
