  Q: How to replace a master cylinder on Nissan Armada?

  A: Disconnect the cable from the negative battery terminal. Disconnect the electrical connectors for the brake fluid level warning light and the brake fluid pressure sensor. Remove as much fluid as possible from the reservoir with a suction gun, large syringe or a poultry baster. Place rags under the 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 where they enter the Brake Master Cylinder. Pull the brake lines away from the Brake Master Cylinder and plug the ends to prevent contamination. Remove the nuts attaching the Brake Master Cylinder to the power booster. Pull the Brake Master Cylinder off the studs to remove it. If necessary, remove the pin on the left side of the Brake Master Cylinder that retains the reservoir and pull it from the Brake Master Cylinder. Lubricate the reservoir seals with clean brake fluid, then press the reservoir into place on the Brake Master Cylinder body. Install the pin that retains the reservoir. Bench bleed the new Brake Master Cylinder before installing it. Mount the Brake Master Cylinder in a vise, with the jaws of the vise clamping on the mounting flange. Attach a pair of Brake Master Cylinder bleeder tubes to the outlet ports of the Brake Master Cylinder. Fill the reservoir with brake fluid of the recommended type. Slowly push the pistons into the Brake Master Cylinder - air will be expelled from the pressure chambers and into the reservoir. Repeat the procedure until no more air bubbles are present. Remove the bleed tubes, one at a time, and install plugs in the open ports to prevent fluid leakage and air from entering. Install the reservoir cap. Install the Brake Master Cylinder over the studs on the power brake booster and tighten the attaching nuts only finger tight at this time. Thread the brake line fittings into the Brake Master Cylinder. Tighten the mounting nuts to the torque. Tighten the brake line fittings securely. Fill the Brake Master Cylinder reservoir with fluid, then bleed the lines at the Brake Master Cylinder, followed by bleeding the remainder of the brake system. Check the Brake Pedal height and adjust if necessary. Check the operation of the brake system carefully before driving the vehicle. If you do not have a firm brake pedal at the end of the bleeding procedure, or have any doubts as to the effectiveness of the brake system, DO NOT drive the vehicle. Have it towed to a dealer service department or other qualified repair shop for diagnosis.
