Service bulletin SIL 735

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

Altec discovered that during the installation of certain chipper body units on Ford F750 chassis that the chassis brake system may have had brake fluid added that can be incompatible with the original equipment manufacturer type fluid. The addition of a different brake fluid should not affect the braking ability of the chassis. However, mixing two types of brake fluid together is not recommended by Ford. Altec recommends that each affected unit have the brake fluid tested for contamination of two types of brake fluid. Customers can order Brake Fluid Analysis Kit, part number 990956561, to begin the analysis process. The customer will draw a brake fluid sample and ship the sample to a laboratory for the analysis in a prepaid envelope. The results of the analysis will be returned to Altec to be communicated to the customer for further action, if needed.
