Removing R32 Brake Lines

[mystery_kid]

i'm in the middle of trying to remove the calipers to rebuilt them, which obviously requires me to under the line so i can remove the caliper completely

all 3 of the nuts on the line just will not undo, all they want to do is round off. am i meant to bleed out the fluid to relieve pressure?

is there something i'm missing here? because it just doesn't seem like they are going to come off

The connections tend to set with age. I find that grabbing the joint with a pair of vice grips and shocking the vicegrips usually works.

yeah didn't have any vice grips, went and got some and worked a treat

thanks
