• Q: How to replace the hydraulic brake booster on 2008 Chevrolet Express 3500?

  A: The first step to replace a hydraulic Brake Booster starts by applying park brake and blocking wheels. The master cylinder should be detached from the booster while its pipes remain intact before placing it inside the engine compartment. You should disconnect the power Brake Booster inlet hose together with the steering gear inlet hose and power Brake Booster outlet hose from the booster assembly. Begin by removing the stop lamp switch followed by the 4 booster to bulkhead nuts before pulling out the booster assembly together with its gasket. Begin booster installation by placing the new gasket before fitting the booster assembly onto position. Install the 4 booster to bulkhead nuts before tightening them to 36 n.m (26 lb ft). Installation begins with first reinstalling the stop lamp switch followed by the master cylinder. Secure the power Brake Booster outlet hose together with the steering gear inlet hose and power Brake Booster inlet hose while tightening the inlet and steering gear hoses to 28 n.m (20 lb ft). The hydraulic booster bleeding process should begin after the wheels have been unblocked following park brake release.
