Service bulletin SD-04-400_007

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

Service Data - Bendix® Reservoirs The reservoir is a storage tank; its function is to provide a volume of compressed air for braking which will be adequate in relation to the volume used by the brake chambers and auxiliary devices. If the vehicle is not equipped with an air dryer, reservoirs provide a location in the system where the air, heated by compression, may be cooled and the water vapor condensed. Bendix® reservoirs are built in accordance with SAE Surface Vehicle Standard SAE J10. They are made from steel sheet, with stamped heads and rolled shells. The seams are electrically welded, and each reservoir is internally coated for corrosion resistance. Each reservoir is tested at 300 psi hydrostatic pressure. Reservoirs are supplied in various pipe ferrule arrangements and lengths–and in diameters from 31/2-in. to 14-in.–having various volumes from approximately 100 to 7600 cubic inches for tractors and trailers. All ferrules are tapped to SAE dry-seal pipe thread standards. Reservoirs are also supplied in double- and triple-compartment configurations.
