2 Broken Caliper bolts.
 

I have a clunking noise coming from my rear end, and it goes away every time I hit the brakes. I lift the car and discover that a caliper bolt on both rear brakes is broken. What do I do? I can't get the caliper off without cutting the rest of the bolt, and I'm afraid if i do that, i won't have any of the bolt left to work with. Will i be forced to buy two hub assemblies?
