But you are correct, the further out the brake pad post is, the more torque you will get on the brake boss, and the fork or seat stay. The more torque, the more twisting you can get. This is one reason that cantilever brakes are commonly toed in; as the fork/stays twist, the brake pad becomes flatter on the rim. By the way, I use cartridge pad holders so that I don't have to reset everything when installing new pads. Oh, and nice polishing job.
Good points -- yes -- these arms do sit out a little further from the fork -- or at least the brake shoe mounting interface does. The brake shoe post is definitely closer though -- with these arms, the brake shoe will touch the inside of the fork/stays when the brakes are open. With the more common Shimano cantilevers on it, the shoes are far enough forward of the fork that they don't touch, and open wider.
