Known issues on the 1985 Brigadier. The truck's federal record is empty, and so is its complaint history at NHTSA. The manual's value is the reference work it does. Each diesel comes with procedures, specifications, torque values, wiring diagrams and diagnostics, and the chassis sections cover the short conventional and low tilt cabs, the frame, suspension, driveline and electrical system, which is the material a shop reaches for when a truck of this vintage comes off the road.
