On my mid-80's touring bike, I'm having some trouble getting the brakes set up. They are old-style, wide profile cantis, with post-style brake pads. One of the rear brake pads is always out of alignment, as if it has too much toe in. Since they are the post style brake pads, I don't have any adjustment to correct for this. I'm getting extremely premature wear on the one brake pad, and I can't get it set up as close as I'd like to the rim.
Is this the nature of the beast? or do I have something wrong here? Is there any way to adjust it or bend it back?
