Here's the bracket from the passenger (right) side front brakes on my Subaru Impreza. Both (17mm) bolt heads snapped off when I tried to remove them using a socket using manual pressure only, no impact wrench, though I couldn't budge them with just the ratchet and had to use a breaker bar (which deserves its name...)
Fortunately although the heads came off, I was replacing the rotor anyway and so could get the bracket out with the rotor. So the bolt stubs are available to hopefully grip & get them out.
Looking for advice on how to proceed with this from here. I've already started to soak these using PB blaster - should I try to spin these out using eg a vice-grip and the bracket in a bench vice? Use heat? Some other method?
I would ideally like to preserve the bracket. But if the advice is just to replace it that is by no means unacceptable.
Also when I eventually go to reassemble this, should I use something like Permatex anti-seize to prevent future problems?
