2006 Chevrolet Monte Carlo Brake Master Cylinder Parts Questions & Experts Answers

• Q: How to overhaul the brake master cylinder on 2006 Chevrolet Monte Carlo?

  A: First disconnect the Brake Master Cylinder then mount its flange in a vise while keeping the primary Piston accessible in the back. Before removing the cap and diaphragm you need to clean the reservoir area around the cap. Check the cap and diaphragm for cuts, cracks, nicks, or mischief and replace them if necessary. Use a smooth instrument to push the primary Piston down until you disconnect the Piston retainer and primary Piston system from the cylinder base. Securing the cylinder ports blocks both inlets and outflows. Supply low pressure non-lubricated filtered air into the front outlet port to extract the secondary Piston together with the primary and secondary seals and return spring. Throw away the major Piston pieces plus the support plate from the second Piston. Use denatured alcohol to clean all parts of the master cylinder assembly plus secondary Piston and return spring while preventing abrasive particles from entering. Check the master cylinder for damage throughout including its bore, inlet and outlet ports, Piston, and the spring system before replacing the unit if you find problems. Use filtered non-lubricated air to dry all components after you apply delco supreme 11(R) brake fluid from a sealed container through the master cylinder bore, secondary Piston bore, return spring, and all parts for assembly. Put the secondary Piston primary seal parts and new secondary seal onto it before placing the return spring along with this assembly into the cylinder bore. Finally place the new primary Piston assembly. Apply the flat end of a tool to push down the primary Piston before adding the new Piston retainer. Then reinstall the master cylinder reservoir with its diaphragm and cap before returning the master cylinder to its place.
