BRAKE SERVICE PROCEDURES FOR 1997 GMC Yukon AUTOMOBILES
Power Brake Units -> Bendix Brake Booster -> General Service

Additionally, care must be taken not to mix the fluids of the booster hydraulic system and brake hydraulic system as the fluids are not compatible.
If the power unit fails, the brakes will still operate, as the convention...
