Hello,
I've got the rear wheels off, the car on jack stands and I'm ready to go. The fittings soaked overnight with WD-40 on them (oops! - maybe should have used penetrating oil

). In fact, I was able to just now loosen the nut on the right brake line (haven't tried the left one yet).
But I have 2 questions: 1) the line is wanting to twist when I loosen the nut. How do I counteract that?, and 2) what can I use to plug the line when I am fitting the new caliper?
Thanks,
