What's wrong?
The air disc brake caliper on a 2018 Wabash National Van trailer holds the brake pads at the wheel end. When the air brake system applies braking force, the caliper squeezes the pads against the rotor so the trailer can slow in a controlled way. The caliper depends on properly tightened mounting bolts to stay fixed to the axle hardware.
On these trailers, MPA/MTA suspensions with Meritor EX225 brakes were built with some caliper bolts that did not meet the required torque specification. That means the bolts were not tightened enough during assembly. If the bolts loosen further, the caliper can pull away from its mounting flange, which affects braking performance and can cause the brake system to default to spring control.
What you notice depends on how loose the hardware is. A visual inspection can detect the issue by finding loose or missing caliper bolts, or a caliper that is no longer seated correctly on its mounting flange.
Who's affected?
The brake-system scope includes the air disc caliper and the broader air-brake system for the same trailer model.

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?
Loose caliper bolts can let the caliper detach from the mounting flange. If that happens, braking ability is lost and crash risk rises. A visual inspection can find loose or missing bolts before detachment, so schedule the inspection soon and have the bolts checked. Repair is free at any franchised Wabash National dealer.
What should I do?
- Check your VIN to confirm your 2018 Wabash National Van is included in this recall.
- Contact a franchised Wabash National dealer to schedule the free brake-caliper-bolt inspection and repair that addresses improperly torqued bolts.
- Bring the recall notice if Wabash National sent one. Reference recall number 17V633 when you call.
- Drive cautiously until the repair is complete, and leave extra following distance because a detached caliper reduces braking ability.
- Call Wabash National customer service at 1-765-771-5300 with questions about recall number 17V633.
What happens at the repair
At the dealer, a Wabash National technician inspects the brake caliper bolts on the Meritor EX225 brake axles and replaces any bolts that are loose or missing.

Frequently asked questions
What is recall 17V633?
Recall 17V633 covers 314 2018 Wabash National Van trailers with MPA/MTA suspensions and Meritor EX225 brakes. The brake caliper bolts were not properly torqued, which can let the caliper detach from the mounting flange. Wabash National dealers inspect the bolts and replace loose or missing bolts for free.
What should I do if my 2018 Wabash National Van is on this recall?
Check your VIN to confirm your specific trailer is included in recall 17V633. If it is, contact an authorized Wabash National dealer to schedule the brake caliper bolt inspection. Reference recall number 17V633 when you call. The dealer repair is free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to complete recall repairs at no cost, and Wabash National's remedy says dealers will inspect the brake caliper bolts and replace loose or missing bolts free of charge.
What is the safety risk?
The risk is reduced braking ability if a brake caliper detaches from the mounting flange. Recall 17V633 says improperly torqued caliper bolts can allow that detachment, which would cause loss of braking ability and increase crash risk. Have the bolt inspection completed before normal service use.
