Service bulletin RSB 530

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Daimler Trucks North America, LLC has decided that a defect relating to motor vehicle safety exists in specific motorhomes built on Freightliner Chassis (NHTSA 18V 353). In response, Newmar Corporation is releasing recall NHTSA 18V 505 and TC # 2018-401. Issue: On certain motorhomes equipped with air disc brakes, the brake caliper mounting bolts may be incorrectly torqued. The caliper bolts may loosen, which may lead to the caliper detaching. Insufficiently torqued fasteners may not provide adequate clamping force between the brake caliper and brake anchor plate, potentially resulting in reduced brake effectiveness. This scenario would result in greater stopping distances, increasing the risk of a crash causing injury and/or damage to property.
