Now on the inside, follow the clutch pedal up to where it meets the master cylinder. You might be able to see the moisture on the rubber boot. This is how you will know that the master cylinder is faulty, broken, or bad. Remove the pin with pliers and slide the round pulley off.

Now you can pull the master cylinder out completely!

To put in the new one, reverse these directions. Pump the clutch a BUNCH of times to get all the air out (pump about 100+ times).
