      Not a roadie so not sure, but looks like there’s not a lot of room to play around with other calipers, feels like you’re about to upgrade your wheel to a larger size

      Are ya sure its not for a Mafac style brake? Some road brakes require a specific boss height. Cane Creek licensed or bought the design to some recent brakes that I think use a dif height. If not, old school Mafac style, which builders do cater to today, def require a dif boss height.

      Axle-brake boss sizes – 700c/622mm 283mm, 650b/584mm 265mm, 26″/559mm 253.5mm

      I bet they’re the wrong forks for the frame

      Hard to tell but looks like v-brakes are needed here?

      Although googling pictures of cantilever brakes I’d say many would come up lower than those examples

      this definitely feels like it’s the wrong fork.

      have you tried v-brakes. those brake boss look so high

      Could be that the rims are too wide. Older canti cross frames had like a 17-19 internal width rim. Or, you need to change the orientation of the cps washers. If you have the wider concave spacer inside the brake on the pad post, move it to the outside.

      Just buy new cantilever brakes. There are different types out there that can be adjusted even more

      My only guess is that the fork has the older, narrower cantilever mounts and you need to find 1990s or earlier era brakes to work.

      I always liked those smooth post shimano deore cantis. Easy to set up once you got the hang of it.

      Edit: possibly the fork is designed for a 27” wheel

      not the greatest fix, but if you want to keep that fork/rim setup you could probably use Paul Component MotoLite v-brakes. they give about the most pad positioning options of any brake I’ve ever seen. not cheap tho.

      I’m almost certain that it’s because the rim is too wide. Those old bikes using cantis commonly had like 15 or 17 mm internal width aluminium rims.

      I don’t recognize the model, but because it’s carbon I suspect it’s at least 19 mm internal width. Also consider that carbon rims have thicker material than aluminium, so a “19 mm” carbon rim rim will be several millimeters wider than a “19 mm” aluminium rim.

      When the rim is too wide, the cantilever cannot turn as far as it’s designed to do. If it could turn, the break pad would go lower.

      Not sure how we arrive here, but this particular fork/wheel/brake aren’t compatible. Others will be. Brakes are usually the cheapest thing to swap, so shop for a brake with a lower adjust range and try things.

      Avid or shimano v brakes run $15, work fine. Change to v brake likely requires a different (long pull) lever.

      Would removing spares on the brake shoe and placing the spring in to the highest hole work?

      Did you measure the canti post spacing? Older frames had the posts much closer together and won’t work with modern cantis that are designed for ~80mm spacing.
