I have searched for some details on how to extend a brake line but only got some vague bend it type of answers so I was hoping to get some specifics. I am a non-wrench son-of-a-gun so use small words and type slowly

I am getting some 4.5" pull back risers for my 2004 883xl. I think the wires are all going to be fine without messing with them but the brake line looks like there isn't much slack. I don't really want to buy a new brake line if I don't have too. Question is, how do I extend it? Can I get a new hose for above the rigid part? How do I get that hose off to repace?

Any help is appreciated.
