How to replace the hydraulic brake booster on Chevrolet Avalanche 1500?

The procedure starts with wheel blocking and application of the park brake before proceeding with the booster replacement. Start by disconnecting the hoses from the inlet steering and return parts of the booster assembly and afterwards remove the master cylinder (Master Cylinder Replacement (Vacuum Boost) master cylinder replacement (Hydraulic Boost)). Before extracting the booster assembly and gasket you must first detach the stop lamp switch and the four booster to bulkhead nuts. Place the new gasket firstly then position the booster assembly before tightening each of the four booster to bulkhead nuts to 36 n.m (26 lb ft). After reinstalling the switch and cylinder you must reattach the return hose with both steering equipment and inlet tubing connections. The hydraulic booster bleeding process must be completed together with park brake release and wheel unblocking. The use of brake fluid requires attention because it causes damage to paint and electrical parts while ensuring the right fluids are used for the hydraulic Brake Booster and master cylinder to prevent seal damage.
