So MAITOY is almost finished…a couple more days and it should be online at Circle A. Just have to wait for the next stable release of JSXGraph (.79) before I upload it as it is dependent on some of the new features. A couple more minor changes to make to the background paper as well.
Hopefully it is intuitive as I think it is. It’s really hard to see what something really looks and feels like with fresh eyes when you’ve been staring at it for three or four weeks. There’s no getting around the subject being confusing if you don’t know anything about brakes, but the goal is that someone with a minimal understanding of brakes can spend a few minutes and come up with a sense of how to approach adjusting their own brakes.
pfffffffft 
This is a really great tool. I love the visualization. For clarity, do you define mechanical advantage as power out/power in, or distance out/distance in? The graph seems to put to rest the myth that a longer straddle cable makes for a more powerful brake.
Never mind. I just read your paper that defines MA as a force multiplier.
Very nice work. Did you do any experimentation with straddle cable holder width and low profile cantis?
Excellent tool, referenced on the CTC (Cyclists Touring Club — UK) forums, eg http://forum.ctc.org.uk/viewtopic.php?f=5&t=57410&p=482118#p482118
Hi, is the tool actually working? I can`t apply any adjustments and it looks very different from your screenshot.
Changes in web standards broke this. There is a mostly fixed version running on Chapman Cycles website. I think everything works except the scales:

Perfect, thanks a lot!
Just another question:
I use extra wide yokes (50mm width – http://www.sheldonbrown.com/images/yokewide.gif). How do I consider this width when adjusting the tool?
Also, my OP distance is 23mm which is not within the adjustment range of the tool, but I see that this does not have a strong impact, right?
Thanks!
