- Summary
- The rear emergency glad hand was improperly connected directly to the rear air tank rather than to the emergency port of the task valve. Consequently, if the air supply to the lead trailer became disconnected, the emergency brakes would be applied but the rear trailer"s would not. A heavy brake application would cause the rear trailer to push the lead trailer forward, increasing the vehicle braking distance, and creating the potential for a jack knife.
- Remedy
- Dealer will inspect and, if necessary, modify the connections in the braking system, without charge to owner.
- Notes
- Vehicle description: semi-trailers.system: air brakes; emergency glad hand.consequences of defect: increased braking distance may lead to a vehicleaccident and personal injury.

Has your Trailmobile been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Trailmobile dealer can also check your VIN. Recall repairs are free.
