If there is a leak anywhere in the hydraulic system, you will need to replace the entire assembly. You buy it from Ford complete, with clutch master/line/slave cylinder already assembled and sealed. There is no method for bleeding the hydraulic system on these trucks (at least not successfully).

I agree, I had this problem after my tranny swap. After trying to bleed the system for a few hours with no luck I went and bought a pre-bled unit.

The secret to bleeding tough slaves is to do it backwards.

Yup, push the fluid UP from the slaves bleeder to the master. Because they're kind of on top of each other, trapped air can be hard to remove as it's a race to fight the rising bubble.

Works every time! I use a Giant Syringe (I've got horses ) and by forcing the fluid in the bubble rises with it into the master.

Even a pre-bled slave can give you trouble because of the amount of air in the line.....

Never heard such a thing. Sounds like it would work! Thanks for sharing.

took everything back out to check the clutch disc, everything was fine, turned out the clutch hydraulic system want leaking but was very weak, pre-bled kit from ford fixed it right up.
