How to service and repair the Brake Master Cylinder on GMC Savana 2500?

Place the Brake Master Cylinder's mounting flange into the vise with care to work on its backside and the primary Piston. Connect suitable fittings to the master cylinder ports using the right seat connections to allow hose attachment. Then remove the cap and diaphragm from the reservoir. Connect transparent hoses to the required fittings on the master cylinder then direct them into the reservoir for a service repair. Insert both brake fluid hoses into clean delco supreme 11(R) brake fluid (GM P/N 12377967) until they reach halfway into the reservoir and submerge their ends fully. With a smooth round-ended tool, press and release the primary Piston multiple times while monitoring fluid output from the ports. The force needed to push the Piston will build up while its movement becomes limited as air comes out of the primary and secondary Piston chambers. Perform this action until the ports show continuous flow of fluid without bubbles. Return the master cylinder reservoir cap and diaphragm before detaching the fittings and hoses from their ports. For cleanup, cover the master cylinder with a shop cloth and take it off the vise.

How to bench bleed the brake master cylinder on GMC Savana 2500?

You can service the Brake Master Cylinder by placing its mounting flange in a bench vise while having easy access to the primary Piston cavity. Put the master cylinder reservoir diaphragm aside and install suitable fittings to the master cylinder ports to connect hoses. Join clear tubes to these ports and feed them into the brake fluid storage space. Submerge the brake fluid hoses ends deep into a clean sealed container of delco supreme 11 brake fluid before pouring at least half of the reservoir capacity to match. Press the primary Piston of the tool every 25 mm (one inch) into action and watch the fluid exit the ports using a round shaped smooth implement. Depressing the primary Piston becomes harder and its downward travel narrows as you bleed the air out of both Piston chambers. Perform this stage of bleeding until the valves release fluid without creating air bubbles. Replace transparent hoses in the reservoir then put on the diaphragm and reservoir cap. Next take off fittings with hoses from ports before leaving the master cylinder in the cloth and removing it from the vise.
