It didn't move much, but enough to take away from loosening the bolt. And are there any household appliances that loosen rusty bolts. Having trouble getting the wheel cylinder bolts removed. Even the brake line is a being a PIA to remove. I'm barely able to turn the brake line loose about a 1/4 turn every 5 mins. It's really stuck on there.

Edit: Yeah, I think I may stop for now since I'm starting to strip the brake line fastener.
