I have just been fitting some replacement forks to my work bike (road). The new forks have braze ons for cantilever brakes which I thought would be ok as I have some old cantis from an old MTB. All was going well until I went to fit the brakes, I have a problem. When I slide the brake onto the stud there is not enough room for the brake and block next to the wheel. I can slide the brake on but can see that I will not be able to adjust the block to contact the rim correctly. The blocks are quite thick and have a threaded post to mount onto the brake. There are also no spherical washers to adjust the pad. The set-up looks so wrong that I thought that MTB cantis and Road cantis must be different but I have done a quick search and I don't think so. Any help or recommendations will be greatly appreciated.
