The defect
Polar Tank Trailer, LLC. (Polar) is recalling certain 2018 SRJ7 trailers manufactured with Meritor MTA/MTP trailer suspensions. The brake caliper bolts on these axles may not be properly torqued which can allow the caliper to detach from the mounting flange.
The risk
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.
