The Brake Master Cylinder is located in the engine compartment, mounted to the power brake booster. Begin by removing as much fluid as possible from the reservoir using a syringe or an old turkey baster. Place rags under the fluid fittings and prepare caps or plastic bags to cover the ends of the lines once disconnected, taking care to avoid spilling brake fluid, which can damage paint. Loosen the fittings at the ends of the brake lines where they enter the Brake Master Cylinder, using a flare-nut wrench to prevent rounding off the corners. Pull the brake lines slightly away from the Brake Master Cylinder and plug the ends to prevent contamination. Remove the nuts attaching the Brake Master Cylinder to the power booster, then pull the Brake Master Cylinder off the studs and out of the engine compartment, again being cautious not to spill fluid. If installing a new Brake Master Cylinder, remove the reservoir from the old one and transfer it to the new unit, ensuring to install new seals. Before installation, bench bleed the new Brake Master Cylinder by mounting it in a vise and attaching bleeder tubes to the outlet ports, filling the reservoir with the recommended brake fluid. Slowly push the pistons into the Brake Master Cylinder to expel air into the reservoir, repeating until no more air bubbles are present. After removing the bleed tubes and installing plugs in the open ports, install the reservoir cap. Position the Brake Master Cylinder over the studs on the power brake booster and tighten the attaching nuts only snugly at this stage, ensuring a new O-ring is installed into the sleeve of the Brake Master Cylinder. Thread the brake line fittings into the Brake Master Cylinder, adjusting the position slightly if needed to avoid stripping the threads. Fully tighten the mounting nuts and brake line fittings to the specified torque. Fill the Brake Master Cylinder reservoir with fluid, then bleed both the Brake Master Cylinder and the brake system by having an assistant depress the brake pedal while loosening the fitting to allow air and fluid to escape, repeating until the fluid is clear of air bubbles. Keep rags handy to catch any fluid, as brake fluid can ruin painted surfaces, and rinse the area under the Brake Master Cylinder with clean water after bleeding. Finally, test the operation of the brake system carefully before returning the vehicle to normal service.
