mc plunge rod

Unbolt your master cylinder from the 4 studs on the firewall. Leave the nuts on the end of studs put a spacer (approx 1/2")between your master cylinder and the firewall. Remove your brake light switch and then pull the brake pedal towards you. This should pull the push rod out of the back of the master cylinder. On some original masters there is also a spring and grommet that will prevent removing the rod all the way until the master is off the car.

Make sure you remove the brake light switch before you pull the brake pedal or you can damage your switch.
