What's wrong?
The air disc brake caliper on a 2013-2015 Wabash National Van trailer is the clamp that presses brake pads against the disc on the axle. When the trailer air brake system applies pressure, the caliper squeezes the pads onto the disc so the wheel end slows in a controlled way. The caliper has to stay bolted tightly to the axle flange for that brake to work correctly.
In NHTSA campaign 15V791, the problem is loose caliper mounting hardware on certain Meritor EX225L2, Meritor EX225L+, and Bendix ADB22X brake assemblies. The bolts were not tightened to specification. Loose bolts can back out during service. If enough bolts come out, the caliper can separate from the axle flange, leaving that wheel end without its normal braking force and allowing loose brake parts to move near the axle.
There is no warning sign before failure. A driver or fleet shop should treat any missing, loose, or shifted caliper hardware as a repair issue, but the recall filing does not identify an earlier driver-facing symptom.

Not every 2013-2015 Wabash National Van trailer is on the list. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
If a brake caliper detaches from the axle flange, braking performance drops and the risk of a crash increases. There is no warning sign listed before detachment, so use extra caution and call the dealer for current recall instructions if your VIN is included. Repair will be free at any franchised Wabash National dealer once available.
What should I do?
- Check your VIN to confirm your 2013-2015 Wabash National Van is included in this recall.
- Contact Wabash National customer service at 1-765-771-5404 to confirm current repair availability before scheduling dealer work.
- Reference recall number 15V791 when you call Wabash National or the dealer.
- Schedule the free brake-caliper bolt inspection once Wabash National confirms the remedy is open; the inspection checks bolts that can loosen and let the caliper detach.
- Drive cautiously until the inspection is complete. Leave extra following distance because a detached caliper reduces braking performance.
What happens at the repair
Once the dealer repair is available, a Wabash National technician will inspect the brake caliper mounting bolts and tighten any bolts that are not secured correctly. Parts and labor are covered under the recall. Wabash National's filing says the recall began on January 11, 2016, but the remedy status provided here is still under development, so confirm availability before arranging service. Owners who paid for this repair before the owner notice should follow the reimbursement instructions included with that notice and contact Wabash National customer service with repair documents.
