Home made Hydraulic Clutch Setup

At some point you're just going to have to buy some crap, put parts on it, see what it does, and go from there. Or buy a proven commercial kit or put the OEM mechanical stuff in. The OEM stuff runs for 50-80,000+ miles with no maintainance or failures. Commercial hydraulic kits same if not longer. How often do you really think you're going to need to swap out leaking parts?

I agree. The amount of time you spend reverse engineering this stuff is not worth what you get on the other end. Plus, no one is going to know (or care) whether you bought a kit or pieced one together yourself.

Again, I've had an American Powertrain hydraulic throwout bearing in my Coronet for over three years and have put 1,000s of miles on the car - not one drop of fluid has leaked out of the system.
