Brake Mounting

[zactor29]

I searched the forums but couldn't find anything to help me out. I recently got a great deal on a Magura Hydro-Stop brake on e-bay. It's brand new and has all the componants but, of course, there's a problem. I have a Profile wheelset with a Yuni frame and I don't know how to go about mounting the brake on. Since the frame is alluminum the guy at my local bike shop said the frame would need to be heat treated after welding brake mounts on to re-stregthen it. Also I'm not sure I want a disc brake but I'm not really sure of my options with this equipment. Any help on what I can do, how to do it, and price estimates would help me out immensely. Thanks so much,
Zac
