In order to dismantle the Brake Master Cylinder, first the battery and housing of the air filter have to be pulled off. Remove the electrical connector that supplies power to the fluid level warning switch and if the transaxle is a manual type, also remove the clutch fluid hose and plug the line. Expel as much fluid from the reservoir as is possible utilizing a syringe. Put the rags at the bottoms of the fittings and gather caps or plastic bags, intending to cover the ends of the lines once removed. Remove the fittings at the end of the
Brake Lines which feed into the Brake Master Cylinder if at all you have not rounded the flats, use the flare nut wrench to do this. Remember that brake fluid harms the car's paint and apply some precaution by covering any naked part of the body and preventing fluid spillage. Disconnect the brake lines from the Brake Master Cylinder by pulling the brake lines as far as possible and securing the free ends with caps. Loosen and take off the nuts that hold the Brake Master Cylinder to the power booster, and gently, but safely, slid it off the studs without spilling any of the fluid. To bleed, for instance, install the new Brake Master Cylinder on a bench via a vise and fixed bleeder tubes on the outlet ports. Add the type of brake fluid recommended for the specific car into the reservoir and gently pump the pistons back into the Brake Master Cylinder to force out the air into the reservoir in a cycle until no formation of bubbles is observed. Also, the bleed tubes, the open ports should be plugged, and on the final process the reservoir cap is put on while the bleed tubes are removed one at a time. Place a new O-ring seal in the Brake Master Cylinder and lubricate same with silicon grease as well as the bore of the power brake booster. The Brake Master Cylinder should be positioned over the studs on the power brake booster, and some nuts have to be tightened with the fingers. Insert the brake line fittings to the Brake Master Cylinder, but slightly adjust the position when threading in and out in order to avoid stripping of threads. Loosely install the brake line fittings and then tighten the mounting nuts to the indicated torque value. You will then pour fluid into the Brake Master Cylinder reservoir, then procedures follow bleeding the lines coming from the Brake Master Cylinder then the rest of the brake system. To bleed the lines take a bottle and have an assistant put pressure on the
Brake Pedal when loosening the fitting to let air and oil come out until the oil is free from air. After doing this, let the assistant give back the gear pedal to their normal position after you have tightened the fitting. Last but not the least, rejoining the battery connection and the other relearn processes that were performed earlier.
