How to remove and install a master cylinder on Ford Mustang?

Brake fluid may damage paint, so cover all painted surfaces and avoid spilling fluid during the procedure. To remove the brake master cylinder, start by removing the mounting fasteners for the air conditioning accumulator/drier and siphoning the brake fluid from the brake master cylinder reservoir. Unplug the electrical connector for the fluid level sensor and, if applicable, remove the hose from the fluid reservoir leading to the clutch master cylinder. Place rags under the brake line fittings, then unscrew the tube nuts at the brake master cylinder, and plug the ends of the lines to prevent contamination. Remove the brake master cylinder mounting nuts and detach it from the power brake booster. Discard any remaining fluid in the reservoir. If installing a new brake master cylinder without a reservoir, transfer the reservoir from the old brake master cylinder to the new one using new seals. Bench bleed the new brake master cylinder before installing it. Mount the brake master cylinder in a vise and attach a pair of brake master cylinder bleeder tubes to the outlet ports. Fill the reservoir with the recommended brake fluid, and slowly push the pistons into the brake master cylinder to expel air from the pressure chambers into the reservoir. Repeat until no more air bubbles are present. Remove the bleed tubes, install plugs in the open ports, and install the reservoir cap. Install the brake master cylinder over the power brake booster studs, tighten the mounting nuts, and thread the brake line fittings into the brake master cylinder. Fully tighten the mounting nuts and brake line fittings securely. Fill the brake master cylinder reservoir with fluid, bleed the brake master cylinder and brake system, then rinse the area under the brake master cylinder with clean water. Test the brake system's operation before using the vehicle normally.
