How to replace the vacuum brake booster on GMC Sierra 3500?

The replacement process starts by applying the parking brake then blocking the wheels.

First remove the Pushrod retaining clip from the brake pedal stud then take off the stop lamp switch and the Pushrod from the same stud. Take out the vacuum booster while discarding its gasket by removing all four booster mounting nuts. Set a new gasket over the booster before installing the vacuum booster unit. Secure the 4 vacuum booster mounting nuts by tightening them to 33 nm (24 ft. Lbs.). Resume connection between Pushrod and the stop lamp switch through their matching point on the brake pedal stud while inserting the Pushrod retaining clip . Join the vacuum hose to the Brake Booster check valve then put back the master cylinder. End your process by letting go of the park brake then free the wheels.
