Your clutch slave cylinder is leaking and your fixing to be walking,but go under your truck on passenger side,theres your slave cylinder bolted onto your transmission,it has a rubber cover on it,also clutch line connected to it,if its leaking,then it needs to be replaced,remove clutch line,then remove 2 bolts holding it onto the transmission,attach clutch line to new slave cylinder,then bolt it to transmission,fill clutch master cylinder with new dot 3 brake fluid,yes you do use brake fluid,then bleed.Part is 15.99 at autozone.
You may have to re-fill the reservoir to prevent sucking in air into the lines, so keep your eye on the fluid level as you perform the bleeding.
If the hydraulic lines are empty when beginning this procedure, it may take several pumps at the pedal before any fluid appears at the bleeder valve. In this initial pressurizing stage, you may opt to remove the valve completely and use your finger as a stopper to help expedite the process by eliminating repeated opening and closing of the valve. Once fluid appears however, replace the valve and proceed with step 4.
With the pedal fully depressed, open the bleeder valve with the correct size open end wrench to release the fluid and then close the valve before the pedal is released.
Be careful to have the bleeder valve fully closed before your assistant releases the pedal (even part way) or air will be sucked in through the bleeder valve and you will defeat your purpose.
Continue to repeat the bleeding process until the fluid coming out is clean and free of any air bubbles.
