How to replace the hydraulic brake booster on 2004 GMC Savana 3500?

Before starting the hydraulic Brake Booster replacement you must set up the park brake and block the wheels. When replacing the booster sediment you can move the master cylinder out but keep its pipes connected and place it in the engine space. You should disconnect the 3 hoses leading to the power Brake Booster assembly after unplugging the stop lamp switch and removing the 4 bulkhead nuts to take out the assembly along with its gasket. Put the new gasket in place and place the booster assembly. Tighten the 4 booster to bulkhead nuts to 36 nm (26 ft. Lbs.). Reverse the stop lamp switch position then secure the master cylinder. After that connect the power Brake Booster outlet hose plus steering gear and power Brake Booster inlet hose. Both inlet hoses require torque to 28 nm (20 ft. Lbs.) for final tightening. Last step is to drain hydraulic fluid from the booster system then free the brake and let the wheels move.
