Broken caliper bolt

[Topless]

Galvanic corrosion is the enemy and penetrating oil, hammer and heat are the solution. Sometimes the corrosion is too severe and you can't save the threads. After soaking overnight again, try heat and a heavy hammer. You might get lucky. If it won't give a time sert installed by an experienced tech will save the hub. It's only money.

Here is a homemade penetrating oil that is tested and performs better than any off the shelf product at 1/10th the price:

I went over and talked to my indy today. He said he has never seen that happen on a Boxster or 911 before. He has seen it on the SUV's, but people drive them year round. He is sure he can get it out. I also asked him to break free the rest of the bolts while it's there. I don't want to go back again. I'm bringing it in tomorrow, so by the weekend I should know what the damage is lol. Thanks for all your help guys
