BRAKE SERVICE PROCEDURES FOR 2002 GMC Sierra 1500 AUTOMOBILES
Power Brake Units -> Delco Brake Booster -> General Service
Vehicle: 2002 GMC Sierra 1500 4.8 V8 GAS

Additionally, on models with hydraulic assist brakes, 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 brak...
