How to replace the hydraulic brake booster on GMC Sierra 1500?

Before starting the process of replacing the hydraulic Brake Booster apply the park brake and block the wheels. A technician should disconnect all hoses from the booster assembly starting with the inlet hose and steering gear and return hoses before master cylinder and stop lamp switch removal (part number 123456). Start by taking out the booster assembly combined with its gasket after stripping the four booster to bulkhead nuts. New gaskets should be placed before you install the booster assembly and tighten its four booster to bulkhead nuts to 33 nm (24 ft. Lbs.). After installing the stop lamp switch (part number 123456) and master cylinder users should connect the return hose to the steering gear and inlet hoses in succession. Close the hydraulic booster system for bleeding then take off the park brake and clear up the vehicle wheels. Protect your vehicle from brake fluid exposure by utilizing proper precautions because the substance can harm paint surfaces along with electrical parts while power steering fluid serves the hydraulic Brake Booster system and brake fluid functions with the master cylinder and brake pipes.

How to replace the hydraulic brake booster on GMC Yukon?

A vehicle technician must begin Brake Booster replacement work by executing both the park brake and wheel block procedure. To perform this task disconnect all pipes from the booster assembly with the exception of the steering gear and inlet hose followed by removing the master cylinder (Master Cylinder Replacement) and the stop lamp switch (Stop Lamp Switch Replacement in Lighting Systems). First remove the four booster to bulkhead nuts before taking out both the booster assembly together with its gasket. Users must begin installation by aligning a new gasket followed by installing the booster assembly. Utilize 33 nm torque to screw in the four booster to bulkhead nuts. The installation process continues with stop lamp switch (Stop Lamp Switch Replacement in Lighting Systems) followed by the master cylinder (Master Cylinder Replacement). Restore connections between the steering gear along with the return hose and the inlet hoses. The hydraulic booster bleeding process ends with the release of the park brake and wheel unblocking procedures. Pay attention to brake fluid irritants and choose the appropriate fluid because power steering fluid serves the hydraulic Brake Booster system yet brake fluid operates through master cylinder and brake pipes.
