is it possible to swap the hose/nipples over on a Shimano calliper?

Bog standard SLX calliper, much like all the others.
It would make sense to have the hose on the outer port for routing on the Canyon Nerve Im fitting them to.

Any reason they cant be swapped over?

It’s a hellova question.
Much better than you last 😆 No idea on the answer but interested to find out :O)

I’ve tried it on an XTR caliper & although the thread is the same, the bleed nipple needs to shut off on the bottom of the hole but can’t as the hose hole is drilled to allow fluid through all the time, where as the bleed nipple will only allow fluid flow when unscrewed.

cheers snaps. That sounds conclusive.

Ah well, wiggly hose time it is.

banjo to let you angle it?
