A: To remove the brake master cylinder, start by disconnecting the cable from the negative battery terminal and unplugging the electrical connector for the fluid level warning switch. Remove as much fluid as possible from the reservoir using a suction gun, syringe, or brake fluid-specific poultry baster. Place rags under the line fittings and prepare caps or plastic bags to cover the ends of the lines once they're disconnected. Loosen the fittings at the ends of the Brake Lines with a flare-nut wrench and pull the lines away from the brake master cylinder, plugging the ends to prevent contamination. Remove the nuts attaching the brake master cylinder to the power booster and carefully pull the brake master cylinder off the studs. To install the new brake master cylinder, bench bleed it first by mounting it in a vise and attaching brake master cylinder bleeder tubes to the outlet ports. Fill the reservoir with recommended brake fluid and slowly push the pistons into the brake master cylinder to expel air. Repeat until no more air bubbles are present, then remove the bleed tubes and install plugs in the open ports. Replace the O-ring seal on the end of the brake master cylinder and install it to the booster, tightening the mounting nuts and brake line fittings securely. Fill the reservoir with fluid and bleed the lines at the brake master cylinder, followed by bleeding the rest of the brake system. To replace the reservoir or O-rings, remove as much fluid as possible, unscrew the bolts or carefully pry the retaining tabs to release the reservoir from the brake master cylinder. Replace the O-rings if necessary, lubricate them with clean brake fluid, and press the reservoir into place, securing it with new roll pins if applicable. Refill the reservoir with recommended brake fluid and check for leaks.
