    Yes. There's one that bolts on, made by Weinmann.

    They are hard to find. I made my own adapter, although not as good looking as the Weinmann, it worked. I used two plates cut to match the frame and it just bolts on and can be adjusted.

    That's a neat little gadget! I was going to suggest using clamp-on cantilever bosses.

    They are challenging to come across. Took me about 6 month to find one at a price I was willing to pay. They were offered to me in the $40-$75 range.

    I need those as calipers don't give me enough braking power. I've only found the bolt on kind for the tubular forks like your pic shows. I'm still looking.

    I've got an idea that a U-brake, mounted near the chain stays, might deliver the most elegant solution--low...almost hidden. There's an original Odyssey PITBULL here, just waiting for the 'right' project.

    I would concentrate on setting up a functional the front brake. When you really need to stop, that's the one that does the work.

    Here's a thought: modify a rear reflector bracket to mount the rear caliper brake. Cut it off with a hacksaw, round off the edges with a file, and drill it for the brake bolt. Here are some candidates for the procedure.

    That Weinmann gizmo is pretty cool. Never saw one of them before.

    I gotta wonder if something like that Weinmann adapter couldn't be fashioned by grinding a relief across one of these bad boys, drilling a mounting hole, and adding a stud for the caliper assembly. The cost of this fitting less than two bucks at Home Depot.

    There are a variety of bolt on center pull brakes available. I have several sets. Cost is high but you can find deals. p.jpg s-l200.jpg s-l1600.jpg

    Some older Huffy mountain bikes had a plate that bolted onto the rear triangle that they used to mount cantilever brakes onto frames without braze-ons. I've scavenged them in the past for klunker projects.
