I HATE brake lines

[gramps77]

what do you guys use to get the brake lines loose? Im trying to replace the 3 rubber portions and Ive never had so much work. I'll now need to replace both tube from the proportioner to the rubber hose to the front brakes. Looks like I'll be needing the rear as well. I even used the correct 6 point tube wrenches. Out come the vise grips and that was the only way to get anything loose but the tubing is now screwed. I was replacing only cause one of my buddies had a rear swell so much it wouldnt pass fluid to bleed the rear brakes. Good thing I did, I cut the driver front and it was swelled internally. Pass side was good
I was doing all of this in the first place because I was replacing the master so figured I would now so I didnt need to bleed again later. sorry for the rambling.
back to the original question, How do you guys break em loose?
