Terry,

I converted my CRII clutch to hydraulic last winter for many of the same reasons you listed. In order to have enough pedal travel with some freeplay the pedal sat very high in relation to the brake pedal. It felt like driving a truck. I am very happy with the hydraulic setup. I probably went overboard on re-engineering the setup. I made a new brake and clutch pedal so I could dial in the pedal feel and position I wanted. I ended up with a pedal ratio around 6:1 and I am using a wilwood master and CNC push type slave. I reworked the bellhousing pivot point to swith the throw out fork to a push type. You should be able to use you pull type fork arrangement, you just need to use a pull type slave.

Whether you will need to change the pedal is up to the pedal feeling you want. Since the clutch pedal is set up to pull the cable you will at least have to modify the pedal to push on the clutch master cylinder. The pedal force and stroke is determined by the pedal ratio, Master cylinder piston diameter, slave cylinder piston diameter and the throw out fork travel.

The relationship between these are pretty straight forward calculations. If you need any help or want some pictures of my set up let me know.

Thanks,

Mike
