Known issues on the 1987 Brigadier. This truck stands clean federally, without a recall and without an owner complaint. The manual is left to cover the hardware, which it does thoroughly. Every one of those diesels is covered in procedure, specification and torque value, with wiring diagrams and diagnostics for its controls, and the chassis sections treat the short conventional and low tilt cabs, the frame, driveline, brake and steering systems and the electrical circuits that connect them, across tractor and straight truck builds alike.
