Brake Master Cylinder Removal and Installation

Do not spill brake fluid on the vehicle; it may damage the paint. If brake fluid does contact the paint, wash it off immediately with water.

NOTE:
Press the brake pedal several times to deplete the vacuum in the brake booster.
Be careful when handling the master cylinder. Do not hold it at the piston, or the piston may separate from the body. If the piston separates from the body, then the master cylinder must be replaced. Do not reinsert the piston back into the master cylinder body.
After removal, plug the end of the hose and joints to prevent spilling brake fluid.
