2004 Chevrolet Corvette Brake Master Cylinder Parts Questions & Experts Answers

• Q: How to service and repair the Brake Master Cylinder on 2004 Chevrolet Corvette?

  A: Begin service work on brake master cylinders by locking the mounting flange inside a bench vise for access to the primary Piston at its rear. Install appropriate fittings having required flare seats on the master cylinder ports until they can accept hoses. Simultaneously remove both the master cylinder reservoir cap and attached diaphragm. The fittings should have transparent tubes attached to them before routing into the master cylinder reservoir. Fill the reservoir to a level above mid-point using delco supreme 11 p/n 12377967 or equivalent dot-3 brake fluid obtained from a clean sealed container while ensuring the hose ends remain under fluid. A round smooth tool should be used to press and release the primary Piston to 25 mm (1 inch) depth several times while you watch fluid flow from the ports. The primary Piston requires more effort to compress and travels a shorter distance as air leaves the pistons. Continue operating the smooth tool with its round tip to achieve fluid flow through the ports with no air bubbles present. You should complete the bleeding procedure by removing the transparent hoses from the reservoir then secure the master cylinder reservoir cap along with the diaphragm before removing fittings with hoses from ports while you wrap the master cylinder with a clean shop cloth to minimize spills before taking it out from the vise.
