I've never heard of such a thing as this "hydraulic clutch pedal assembly" but I guess since I was converting a manual transmission setup and the only "change" was changing the throwout bearing from mechanical to hydraulic, and the parts involved in the conversion, I was only looking at the pathway that is commonplace.
I really like this assembly with the little I know about it, as it appears to be straightforward and takes some of the variables out of the equation.
Kudos on top of the continuous string of accolades in the details of your work.
