Repair Procedure: Overview

**This bulletin involves replacing the front brake linings on 2500 series and 3500 series vehicles, the rear brake linings on 3500 series vehicles, and the rear wheel cylinders on 2500 series, 8800 GVW vehicles (sales codes Z2B and Z7B only) that are operated continuously near 75% or greater of the Gross Vehicle Weight Rating. **

Also, because rear brake adjustment is critical to the total operation of the braking system, it is recommended that the customer be made aware of the proper procedures to operate the rear automatic self adjusting brake system. The procedures are outlined in the Owners Manual. The procedure states, "To maintain the correct adjustment, you need only drive your vehicle in reverse and apply the brakes until the vehicle comes to a complete stop."
