Quick Question, need help fast.

OK, hopefully that got your attention. I'm tearing into my ABS unit but need a bit of help.

Those three lines are stopping me from removing the entire assembly, I tried to take them off, but I'm not sure how. They dont seem to just "unscrew" and I'm afraid to turn it to much thinking I might break the line.

So, how do I get those off?

For each line, hold the larger nut with a wrench to prevent it from turning and unscrew the smaller nut.

Perhaps my SC just doesn't like cooperating but thats not working. I've tried every tool at my disposal (also tried lubing it up first & letting it sit) but so far....notta. This entire brake system, scratch that, this entire automobile is proving to be a bigger PITA than it's worth.
