BRAKE SERVICE PROCEDURES FOR 2002 GMC Sierra 1500 AUTOMOBILES

Power Brake Units -> Bendix Brake Booster -> General Service
Vehicle: 2002 GMC Sierra 1500 5.3 V8 GAS

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...
