Start by depressing the brake pedal multiple times to deplete the vacuum reserve in order to remove the brake master cylinder. You can find the Brake Master Cylinder in the engine compartment and it is mounted to the power brake booster. Ensure that you do not use it for food preparation again by removing excess fluid from the reservoir using a syringe or turkey baster. Prepare caps or plastic bags to cover line ends, and put rags beneath fluid fittings. Pulling slightly away from the Brake Master Cylinder, loosen flare-nut wrench fittings at ends of brake lines and plug the ends. The electrical connector for the brake fluid level sensor should be disconnected first, then nuts attaching it to the power booster removed. Be careful when handling it so as not to spill any fluid while removing the Brake Master Cylinder. If installing a new Brake Master Cylinder, tap out retaining pins transferring old reservoir and install new seals. Attach bleeder tubes to outlet ports after mounting it in a vise then bench bleed it before installing new one on your vehicle. Recommended brake fluid should be used on this process as you will need to fill up its reservoir accordingly while slowly pushing pistons into Brake Master Cylinder with your fingers to let air out then repeat until no more bubbles are seen. Remove plugs from open ports and take off bleeding tubes when finished. Thread by hand, tighten mounting nuts finger tight onto power brake booster and make sure that you fully tighten mounting nuts as well as brake line fittings respectively with hand screwing threaded into Brake Master Cylinders. Connect electrical connector of brake fluid level sensor now on go ahead filling fluids into Brake Master Cylinders' reservoirs before bleeding them together with entire braking system altogether, right? Before you use your vehicle test its braking system extensively.
