A third hand makes adjustment much easier, and like wilber says, so does the proper procedure. It took me a while to get it too - I think I found the procedure online.

Once adjusted properly, I learned to really like this brake (on the Dorado it's on the chainstays only). The mechanical advantage is contoured by the cam giving you good closure and swing early in the stroke and serious muscle at the bottom. This has to be the hardest clamping rim brake I've seen, while remaining 'not grabby' unless you really want it. I wouldn't change it, though I do like the idea of a cover.

wilber, maybe post both procedure and pic of cover in the "Hints and Tricks" thread?
