If installing a new master cylinder, remove the reservoir from the old one and transfer it to the new master cylinder. To install the new master cylinder, bench bleed it first by mounting it in a vise and attaching bleeder tubes to the outlet ports. Fill the reservoir with brake fluid and slowly push the pistons into the master cylinder to expel air. Repeat until no more air bubbles are present. Remove the bleed tubes and install plugs in the open ports. Install the master cylinder over the studs on the power brake booster and tighten the attaching nuts. Thread the brake line fittings into the master cylinder and fully tighten them. Fill the master cylinder reservoir with fluid and bleed the master cylinder and brake system. Test the operation of the brake system before placing the vehicle into normal service.

To remove the 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.
