So I'm trying to replace the wheel cylinders and the nuts and brake line fasteners just aren't braking loose. I tried both my line wrenches and my socket wrenches and they don't seem to be doing any good. I already started to strip the brake line fastener so I stopped that.
Do you think some WD40 or acetone sprayed on there would help any? I may have to pick some up in the morning. For now I shall take a warm shower and head to bed.
IMO, the sooner you write-off the rear hard lines, the better. If it was mine and it looked remotely rusted, I'd start with PB blaster where the two hardlines meet in the middle of the axle. If you can win with those, some new hardline would be a good way to start. That way you can..get new hardline in there and just cut the hardline at the wheel cylinder and remove it. Old rusty brake line fittings are very unforgiving, sooner you decide to just replace them the better. In my opinion..
