Re: hyd clutch bleeding
Bench-bleed both. Install. Re-bleed. Enjoy.

Re: hyd clutch bleeding
If I remember correctly, you will want the slave piston pushed in - I had quite the battle getting the system working that I swapped into my truck.

Re: hyd clutch bleeding
I just bled the mc first, then hooked up the line to the slave and bled it the rest of the way. I also pumped the slave side a few times which pushes air bubbles back out through the master. With a hydraulic clutch there is no pre load to worry about.

Re: hyd clutch bleeding
I've had good luck on external slaves by bench bleeding the entire assembly. With the master in a vise I run the line vertically down to the slave cylinder and cycle the slave by hand slowly getting all the air out. Once air bubbles stop coming out the master I extend the slave one last time and let it compress with the bolts as I install it. This pushes any last bit of air up to the reservoir.
This is a simple way and has worked great for me for the slaves that don't have a bleeder.
