when i was running a 32c tyre on my front, the only brake i could get to fit was a single side pull modolo i think but can check, that gradually wore a furrow into the tyre around the bolt when the fork flexed. might want to try a 20c tyre for more clearance, and look for the slenderest cheap caliper you can find.
if i find the one i had in the shed, i’ll post a picture tomorrow, i think it would work…
consider taking apart a caliper and getting in touch with someone who can machine down the tolerance above the tyre/underneath of caliper arms to create more tyre clearance
and/or
Machine the area where the axle of the brake pad sits to allow you to run it higher up that face of the caliper to meet the braking surface of the rim.
(if you cant do it yourself)
If you follow this path make sure it doesnt weaken the structural integrity of the caliper, catastrophic fail will lead to the caliper breaking away from the fork mount and you most likely binning it
My bike has a very tight fork to tire clearence and I sometimes run a clamp-on brake for longer rides when my legs don’t feel like stopping. Not the best looking option but it works a treat.
