  Q: How do you remove the master cylinder?

  A: To remove the brake master cylinder, start by removing as much fluid as possible from the reservoir using a syringe or turkey baster. Place rags under the fluid fittings and prepare caps or plastic bags to cover the ends of the lines once they are disconnected. On manual transaxle models, disconnect the clutch master cylinder supply hose from the brake fluid reservoir. 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. Disconnect the electrical connector at the brake fluid level switch on the brake master cylinder reservoir, then remove the nuts attaching the brake master cylinder to the power booster. Carefully pull the brake master cylinder off the studs and out of the engine compartment, being cautious not to spill any fluid. If installing a new brake master cylinder, unclip the reservoir mounting tabs and transfer the reservoir to the new brake master cylinder. 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 into the reservoir. Repeat until no more air bubbles are present. Remove the bleed tubes and install plugs in the open ports. Install the brake master cylinder over the studs on the power Brake Booster and tighten the attaching nuts finger tight. Thread the brake line fittings into the brake master cylinder, fully tighten the mounting nuts and brake line fittings to the proper torque specifications. Connect the brake fluid switch electrical connector and, if applicable, the clutch master cylinder supply hose. Fill the brake master cylinder reservoir with fluid and bleed the brake master cylinder and brake system. Finally, test the operation of the brake system before placing the vehicle into normal service.
