What's wrong?
The 2011 West-Mark Tanker uses air disc brakes on the trailer axle. In that system, air pressure moves a brake caliper, and the caliper clamps brake pads against the rotor to slow the trailer. The caliper has to stay bolted to its mounting flange so the brake force goes where it belongs.
In recall 17V646, the tanker trailer was built with an MPA or MTA suspension equipped with Meritor EX225 brakes. The brake caliper bolts on that axle were not properly torqued. Loose bolts let the caliper move, and the caliper can detach from the mounting flange instead of holding its position during braking.
There is no warning sign before failure. A driver should not rely on a noise, light, or change in brake feel to know the caliper bolts have loosened.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific trailer.
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. Drive cautiously until the inspection is complete, and schedule it soon. Repair is free at any franchised West-Mark dealer.
What should I do?
- Check your VIN to confirm your 2011 West-Mark Tanker is included in this recall.
- Contact a franchised West-Mark dealer to schedule the free brake-caliper bolt inspection and replacement that keeps the calipers secured to the mounting flange.
- Bring the recall notice if West-Mark mailed one. If not, reference recall number 17V646 when you call.
- Keep extra following and stopping distance until the repair is complete because detached brake calipers can reduce braking ability.
What happens at the repair
At the dealer, a West-Mark technician inspects the brake caliper bolts on the tanker trailer's Meritor EX225 brake axle. Any loose or missing bolts are replaced, and parts and labor are covered under the recall. If you already paid out of pocket for a related brake caliper bolt repair before the recall notice, West-Mark's general reimbursement plan covers documented expenses. Bring the repair paperwork to the service desk and ask how to submit it for review.
