there were a couple of problems with this design, the biggest of which was that this positioned the caliper in the front (like the original) however the caliper was designed to be in the rear. I could have used it in the front, but I would have had to change the balance tubes and bleeders (not a huge problem). I ended up stripping out one of the caliper mounting holes which made me rethink the who design. I also didnt really like the overall surface contact area (rigidity).
