2000 Cadillac Escalade Brake Master Cylinder

You need to apply the parking brake, disconnect the brake pipe and plug the pipes to prevent brake fluid loss or contamination, and then remove the master cylinder nuts, the bracket, and the master cylinder.

You should inspect the cylinder bore for scoring or corrosion. You need to replace the master cylinder if corrosion is present and do not attempt to hone the cylinder bore.

We should avoid using fluid that has a petroleum base and not uses a container that has been used for petroleum-based fluids or is wet with water.

You can fill the master cylinder reservoir, stroke the primary piston about 25 mm (1 inch) several times using a smooth round-end tool, and then level it in the vise and fill the master cylinder reservoir with clean brake fluid.

You can clean the metal parts in denatured alcohol and clean the rubber parts in clean brake fluid.
