Here's a link to a front brake setup I'm working on for my Flattie Chopper. The brake is mostly done, I posted over on John's site some info to help George, thought I might as well put the site up here as well. I've tested this caliper on my Bobber last Fall, it has at least the stopping power of the older '74 Sporty caliper I had been using. Mostly I liked the way this one tucks in behind the girder leg. Just satisfies my sense mechanical beauty.
