Service bulletin TCH-008-044

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

Steps to Prevent Air Brake System Contamination ? Best Practices There are many myths and much misinformation when it comes to minimizing the impact of contamination in the air braking system. Bendix Commercial Vehicle Systems LLC (Bendix) has found that the majority of the procedures available today do not reflect current recommended practices for air treatment and storage systems. Chief among our concerns are the concepts that air system antifreeze or alcohol is often considered acceptable, along with the practice of draining air system reservoirs daily. Refer to Bendix Technical Bulletin TCH-008-042 which strongly discourages the use of alcohol in the air braking system.
