2010 Cadillac Escalade ESV Brake Master Cylinder

The proper way is to install the brake master cylinder seal and the master cylinder, install 2 new brake master cylinder nuts, tighten the nuts to 33 Nm (24 lb-ft), and then fill the brake master cylinder reservoir.

You should use only Delco Supreme 11(R), GM P/N 12377967 (Canadian P/N 992667), or equivalent DOT-3 brake fluid from a clean, sealed brake fluid container.

The procedure is to remove the brake fluid from the brake master cylinder reservoir until the level is below the reservoir supply hose fitting and discard it into an approved container, remove the antilock brake system (ABS) module splash shield retainers, remove the ABS module splash shield bolts, remove the ABS module splash shield, and then release the supply and return hoses from the retainers and remove the hoses from the vehicle.

The procedure is to remove the master cylinder reservoir cap and diaphragm, install suitable fittings to the master cylinder ports that match the type of flare seat required and also provide for hose attachment, install transparent hoses to the fittings installed to the master cylinder ports, remove the transparent hoses from the master cylinder reservoir, install the master cylinder reservoir cap and diaphragm, remove the fittings with the transparent hoses from the master cylinder ports, and then remove the master cylinder from the vise.

The proper way is to install the 3 master cylinder reservoir seals, install the master cylinder reservoir to the master cylinder, install the brake master cylinder reservoir pins and tighten to 8 Nm (71 lb in), and then fill the brake master cylinder reservoir.
