After you have located the clutch slave cylinder, have someone depress the clutch pedal. You should see the piston of the slave cylinder extend somewhat. If it does not, either the slave cylinder is bad, or the master cylinder, or, there is not enough brake fluid in the system for it to operate properly. Check the level in the master cylinder. If the slave cylinder is leaking profusely, it is probably bad.
