What's wrong?
The 2018 Walker Tank Trailer uses air disc brakes with Meritor EX225 brake calipers on MPA and MTA suspension axles. The caliper is the clamp that squeezes the brake pads against the disc when air-brake pressure calls for stopping. It has to stay bolted tightly to the mounting flange so braking force goes into the wheel end instead of moving the caliper itself.
On affected trailers, some brake caliper bolts were not tightened to the required torque during axle production. A torque check that should have caught the condition was omitted in a small number of builds after production volume increased. When those bolts loosen, the caliper can break away from the torque plate or mounting flange, reducing brake performance and causing the system to default to spring control.
The warning sign is usually found by inspection, not by a dashboard alert. Depending on how loose the hardware is, a visual check can show loose, missing, or shifted caliper bolts before the brake assembly separates.

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, causing a loss of braking ability and increasing the risk of a crash. A service inspection checks for loose or missing bolts, so schedule the inspection promptly if your VIN is included. Repair is free at any franchised Walker dealer.
What should I do?
- Check your VIN to confirm your 2018 Walker Tank Trailer is included in this recall.
- Contact a franchised Walker dealer to schedule the free brake-caliper-bolt inspection and replacement of any loose or missing bolts that keep the caliper attached to the mounting flange.
- Bring the recall notice if Walker mailed one. If not, reference recall number 17V833 when you call.
- Ask Walker customer service at 1-800-356-5734 about recall W-6430 or W-6431 if the dealer needs the Walker recall number.
- Avoid operating the trailer until the brake caliper bolts are inspected and secured.
