What's wrong?
The air disc brake caliper on the 2018 Trail King Fifth-Wheel Live Bottom trailer is the clamping part of the brake. It sits on the axle brake assembly and squeezes the brake pads against the disc when air pressure applies the brakes. The caliper has to stay bolted tightly to its mounting flange so the brake force goes into the wheel, not into loose hardware.
On the affected trailers, the Meritor EX225 brake caliper bolts on the MPA/MTA suspension axles were not properly torqued. A bolt that is not tight enough can loosen as the trailer moves and brakes under load. If the caliper detaches from the mounting flange, that brake assembly cannot work as designed.
There is no warning sign before failure. Do not rely on a light, sound, or change in brake feel to appear before the caliper comes loose.
Who's affected?
The brake-system scope is tied to one trailer configuration, with no separate model-year spread.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
Improperly torqued caliper bolts can let the caliper detach from the mounting flange. If that happens, braking ability is lost and crash risk increases. Until the inspection is complete, drive cautiously and schedule the recall service soon. Repair is free at any franchised Trail King dealer.
What should I do?
- Check your VIN to confirm your 2018 Trail King Fifth-Wheel Live Bottom is included in this recall.
- Contact a franchised Trail King dealer to schedule the free brake-caliper-bolt inspection and any needed bolt replacement that keeps the caliper secured to the mounting flange.
- Bring the recall notice if you received one. If not, reference recall number 17V614 when you call.
- Tow cautiously until the inspection and repair are complete. Leave extra stopping distance because a detached brake caliper can reduce braking ability.
What happens at the repair
At the dealer, a Trail King technician inspects the brake caliper bolts on the Meritor EX225 brake assemblies. The technician checks for bolts that are loose, missing, or not properly torqued, then replaces the affected hardware free of charge. The recall repair is available now, so schedule service with a Trail King dealer and ask the service desk whether the trailer needs inspection before it returns to work.
