How to overhaul the brake master cylinder on 2001 Chevrolet Suburban 1500?

Question

Accepted Answer

Secure the mounting flange in a bench vise before starting your Brake Master Cylinder overhaul work while you keep access to the rear of the primary Piston. Before you take out the master cylinder cap you need to clean around the reservoir area but keep the area free of dust. Analyze the cap and diaphragm for any flaws in shape, cuts, fractures, blemishes or deformed parts to replace them as needed. Disengage the master cylinder reservoir part and press the primary Piston towards the cylinder using a rounded tool. Take out the Piston retainer and seal assembly afterward. Connect both cylinder intake ports and the back port while blowing non-lubricated filtered air into the front port using low pressure to eliminate all three seals and components. Take out the primary Piston assembly plus its Piston retainer and seals from the secondary Piston. Before building the master cylinder unit you need to thoroughly clean its interior and exterior with denatured alcohol along with the secondary Piston and return spring. Inspect every part for damage including cracks, scores, pits, or corrosion and replace the whole assembly if finding any problems. Run each part through non-lubed filtered air and insert delco supreme 110 fluid (GM P/N 12377967) or equivalent dot-3 brake fluid into the master cylinder bore, secondary Piston, return spring, and all overhaul components from a sanitized supply container. Fit the new primary seal components over the secondary Piston seal and install the return spring and secondary Piston lubricated assembly into the bore before adding the lubricated primary Piston in place. You should use a smooth tool to compress the primary Piston while installing the new Piston retainer followed by reconnecting all components of the master cylinder before reinstalling it.
