On SRAM the olives thread on to the barb. It’s possible that you may be able to unthread the current one but I doubt it would go back on again and it will already be crushed by the calliper bolt. Easiest way is to just cut the olive and bard off.
Thank you, realised this eventually! Waiting on one hose to finish this, as I ordered the red 22 one, thinking it would fit. Had I been more careful I'd have been able to reuse the old hose but in my rush I cut it a couple of cm too short. Pricy mistake.
