NHTSA's recall notice
As NHTSA's recall record states it for campaign 17V646000.
Defect description
West-Mark is recalling one 2011 2TANCX3A tanker trailer manufactured with an MPA/MTA suspension equipped with Meritor EX225 brakes. The brake caliper bolts on this axle may not be properly torqued which can allow the calipers to detach from the mounting flange. As such, this vehicle fails to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake System."
Safety consequence
If the caliper bolts are improperly torqued and the caliper detaches from the mounting flange, a loss of braking ability would occur, increasing the risk of a crash.
Manufacturer remedy
West-Mark will notify the owner, and a dealer will inspect the bolts, replacing any loose or missing ones, free of charge. The recall began on October 26, 2017. Owners may contact West-Mark customer service at 1-800-692-5844. West-Mark's number for this recall is C17AB.
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.
