The brake master cylinder is located in the engine compartment, mounted to the power
Brake Booster. Begin by removing the air filter housing. Disconnect the electrical connector from the fluid level warning switch. Using a syringe or equivalent, remove the brake fluid from the brake master cylinder reservoir and dispose of it properly, ensuring that brake fluid does not come into contact with painted surfaces as it can cause damage. If spilled, wash immediately with water. Disconnect the electrical connector from the fluid level sensor on the remote reservoir, then remove the remote fluid reservoir mounting bolt. Place rags underneath the fluid fittings and prepare caps or bags to cover the ends of the lines once they're disconnected. Loosen the fittings at the ends of the
Brake Lines entering the brake master cylinder. Using a flare-nut wrench is preferred. Pull the brake lines slightly away from the brake master cylinder and plug the ends. Remove the mounting nuts from the brake master cylinder to detach it from the power booster and then pull it out of the engine compartment. If installing a new brake master cylinder, transfer the reservoir to it. Before installing the new brake master cylinder, bench bleed it by mounting it in a vise. Attach bleeder tubes to the outlet ports and fill the reservoir with brake fluid. Push the pistons into the brake master cylinder until no more air bubbles are present, then remove the bleed tubes and install plugs in the ports. Install a new O-ring on the brake master cylinder and place it over the studs on the power brake booster. Thread the brake line fittings into the brake master cylinder and tighten them. Fill the brake master cylinder reservoir with fluid and bleed it. Attach the remote fluid reservoir, tightening the bolt securely. Reconnect the electrical connector to the fluid level sensor. Reverse the removal process for the remainder of the installation, bleed the entire brake hydraulic system, and test the brake system operation before regular driving.
