Just wondering who's installed an hydraulic handbrake in their fc? Did you make your own kit? or use the ksport universal kit or similar? and how/where did you tie in?

 

A few guys in the racecar tech/drifting section have done it and have pictures. Search and you'll find them on the only page.

pictures of everything I am describing are on that page.

I've done one setup in a 240, step by step went a little like this:
1. Find another pair of rear calipers from a junked 240
2. Machine a new caliper bracket so you can use 2 calipers, way simpler than it sounds. Use the old one for a partial pattern, if you don't have the tools go to a machine shop and I couldn't imagine it would cost you more than 50 bucks total if you've done the homework.
3. Install the adapter/calipers
4. Run the lines from your Hydraulic handbrake's master cylinder to calipers
5. Fill/bleed the system.

you can also run a priority valve on the one brake line that runs under the car to the rear wheels, this is cheaper/easier but one caveat: I've seen some people throw a fit about them at tech inspections.
