They are a large manufacturer of VW off Road stuff. Brakes, Pedal assemblies, etc. They don't have a website to speak of, but check any off-road sand-rail web site and they will be there.
I use www.mckenzies.com; they are a big CNC distributor....look under PRODUCTS>BRAKES. The part number of the hydraulic kit I bought is CNC-320B I think (you would want to verify that)...cost is $130 and it includes the Master Cylinder, the Slave Cylinder, nylon fittings/tubing and installation hardware. On top of that I bought a CNC aluminum reservoir and the rod end. In the end, I routed the nylon tubing from the master cylinder to a little bracket I made and installed (using adel clamps) at the shock tower cross tubes. I then used a standard steel braided wheel brake line to go from the bracket to the slave cylinder. I did this because the slave moves when actuated and the nylon tubing popped out a couple of times. There is also a bracket you can buy that repositions one end of the slave cylinder so that the pull is straight - www.formulanine.com/SlaveSaver/slave_saver.
I will probably do this some time down the road.
My car is here at my business - so if you need I can reel off some digital pics. I am traveling from tomorrow until 9/22 though.
