Broken caliper bolt

[CoBeerToad]

Got the passenger side all done with no problems. Brought the car to the shop to see if they could remove that bolt and they couldn't, so since the carrier is otherwise jacked I'm going to try drilling it out. Can't hurt. I'm moving in 17 days, so nothing like a little bit of pressure to get the job done right.

After reading this thread I think I might change out my rear bolts proactively. I don't think they've ever been done on my car (the fronts were done in '08).

I had the passenger side ones out a couple days ago to check the park brake, and noticed some corrosion / slight reduction in thread diameter along a short part of the length. I put them back in but think it's time.

I notice Pelican sells silver anti-seize to go along with them. I have copper. Is copper a problem in this application?
