Be careful not to spill brake fluid on the painted surfaces. It will damage the paint. If a spill occurs, flush the area with plenty of fresh water.
Thoroughly clean all dirt and debris from the master cylinder cap and the area surrounding the cap.
Unplug the fluid level warning switch connector.
Use a syringe or similar tool to remove as much fluid as possible from the reservoir.
Carefully disconnect the brake lines at the master cylinder.
To prevent line damage, use a line wrench. Regular open-end wrenches are NOT recommended. Take great care not to bend or deform the lines. Plug the lines to keep dirt from entering.
Remove the nuts holding the master cylinder to the booster. Unbolt the 3-way or 4-way union.
When removing the cylinder, take care to recover the clamps, gaskets, etc.
Using a new gasket, install the master cylinder onto the brake booster. Tighten the mounting nuts to 9 ft. lbs. (13 Nm).
Attach the union. Carefully connect the brake tubes, initially threading them into place by hand. Once properly engaged, tighten the fittings to 11 ft. lbs. (15 Nm).
Connect the wiring harness for the brake fluid switch.
Fill the brake fluid reservoir with fluid to the "MAX" line. Check the leakage.
Bleed the brake system. Check again for any leakage.
Check and adjust the brake pedal.
