How to replace the Brake Master Cylinder (Hydraulic Boost) on Chevrolet Avalanche 1500?

Put the park brake on and block the wheels before working on the Brake Master Cylinder (Hydraulic Boost). Put a plug over brake pipe ends to block brake fluid from escaping when you detach the hose connection to the Brake Fluid Level Sensor. You should unhook the brake lines from the master cylinder then seal the open brake pipe ends. Take the master cylinder out of the car by removing its mounting nuts first and then taking out the master cylinder reservoir. To begin installation you need to put the master cylinder reservoir in place first. Before putting the master cylinder back into the vehicle perform a fluid drainage operation called bench bleed. Secure the master cylinder mounting bolts by tightening them to 36 n.m (27 ft lb). Put together the connected brake pipes by adding the rubber caps back at the exposed ends then tightening the fittings to 25 n.m (18 lb ft). Join the brake fluid sensor electrical connector as you run hydraulic brake system bleeding. Complete the job by releasing the parking break and moving the wheels once free.
