Service bulletin RSB 507

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

In response to notification from Ford, Newmar Corporation has decided that a defect relating to motor vehicle safety exists in specific motorhomes built on Ford chassis. On certain motorhomes, the anti-lock brake system hydraulic electronic control unit (HECU) may have missing valve block ball plugs. Issue: This could cause fluid leaks or air ingress during braking, potentially increasing brake pedal travel and/or stopping distances. This could increase the risk of a crash causing injury and/or damage to property.
