Here is a good Clutch bleeding video.
BMW, VW, Porsche Clutch Bleeding - YouTube
You have to bleed from the bottom up to push out the air. I tried to bleeding it with my Motive pressure bleeder from the top. blew out a lot of fluid, but still didn`t get it to work.
Tried the gravity method and it didn`t work either, yet heard of others doing it and it worked.
Bleeding using the R/F Caliper method, would be best to flush the Brakes first so you are not recirculating dirty contaminated fluid into your new system.
Answers might be slow coming, it is the week end.
