So i'm changing my brake rotors and i have 3 of 4 done and I'm trying to remove the caliper guide on the last wheel (front) its 2 19mm nuts and I can not get them to move. I have added a pipe to my wrench for more leverage and nothing is moving. I have some wd40 on there now and will go back out and finnish hopefully before long. Anyone have any Ideas for me? I would love to finnish and I know once I break these loose I can be done in about 15 minutes.
