Service bulletin PIL674

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

Meritor has made an improvement to our Quadraulic brake system. The upgraded caliper uses an improved crossover tube insert that seals directly to the caliper housing, which can reduce the potential for incorrectly seated assemblies that can create crossover tube leakage.
