Great, thanks for the info! To remove the pigtails (it is a small frame) I could just open the coupler & the bleed port on the lever ensuring the lever is in a higher position than the coupler & drain it, right? Then once I removed that bit of hose from the shifter, I just carry on as if they werent there to begin with.
You'll need a new barb and olive (it's the BH-90 ones, olive are the same the barbs come in 2 sizes) as the brake hose nut will be in the way.
Undo the nut partially, about 3 turns or so, then wiggle the hose loose, don't undo the nut fully as you'll risk splattering your wall with hydraulic fluid.
