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