NHTSA's recall notice
As NHTSA's recall record states it for campaign 17V833000.
Defect description
Walker Stainless Equipment Company LLC (Walker) is recalling certain 2018 Tank Trailers, equipped with MPA/MTA suspensions and Meritor EX225 brakes. The brake caliper bolts on these axles may not be properly torqued which can allow the caliper to detach from the mounting flange. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
Safety 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.
Manufacturer remedy
Walker has notified owners, and dealers will inspect the bolts, replacing any loose or missing ones, free of charge. The recall began on January 5, 2018. Owners may contact Walker customer service at 1-800-356-5734. Walker's numbers for this recall are W-6430 and W-6431.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
