Who needs this DuraStar hydraulic ABS manual
Brake technicians and fleet shops use this section to service the master cylinder, hydraulic compact unit and wheel speed sensors and to clear fault codes. It is for factory-trained professionals only.
The manual is emphatic that only factory-trained technicians work on the Full Power Brake system, because trapped air or contamination can cost braking function on the road. Keep the master cylinder reservoir topped between MIN and MAX with fresh fluid, plug open ports immediately, and use a regulated pressure bleeder. After any ECU work, program the unit to the VIN and clear inactive fault codes with the diagnostic software before releasing the truck.
