I understand that I need a longer recessed nut. That wasn't the problem I was coming up against (well, not completely). Instead, the brake shoes where hitting the sides of the fork, and hence not able to sit flush against the fork. From reading above posts I assume I need spacers? That's funny because I suggested that to a local bike shop, and they turned that idea down. Of all of the bike shops I went to there were only two brakes that worked without spacers, a campagnolo and a dura-ace, but both were used and missing barrel adjusters. The final parting word I got from that shop was I needed a "special" brake to accommodate the fork, something more modern built for larger forks.
This all is strange to me because it doesn't seem like the size of the fork would determine whether this was a problem or not. I don't trust my novice understanding on all this, but having gone to multiple shops and seen for myself how the brakes didn't fit I don't really know what to do next. I contacted Leader, but haven't gotten a reply (probably because it's a stupid question).
Could something be wrong with the brake shoes I have?
Also, a recessed nut was supposed to have come with the fork? I guess I missed it and threw it away.
