Summary
Walker Stainless Equipment Company LLC (Walker) is recalling certain 2018 Tank Trailers, equipped with MPA/MTA suspensions and Meritor EX225 brakes.

Consequence
If the caliper bolts are improperly torqued, the caliper can detach resulting in a loss of braking ability, increasing the risk of a crash.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Walker been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Walker dealer can also check your VIN. Recall repairs are free.
