Well today was an interesting day, as we finally got the e3 started again! (will post a vid eventually). However, it appears that I seriously screwed up on this rusted old caliper while I was trying to take it out (I have a new one I want to put in). As I tried to take at those two big bolts (pictured), one of them broke and its pretty darn stuck in there. Any advice on how to take this caliper out? Or do I need to take out the entire shoe, and if I do, how so?
