Glad they solved the problem, sorry you are/were possibly having problems with the Callahan caliper. I priced new rotors from Lexus and Toyota before going with Callahan, but at that point they were waaaaaay more than $140 each. Had that been the case, I would have picked up the new. Seems like they were closer to $250 each. The calipers I received from Callahan were already painted silver (some kind of zinc paint), but rust is not much of an issue living in AZ. Before receiving them I had researched caliper paint too, because I heard other brands were unpainted and famous for getting rusty. Did yours look like the ones I show in the pictures? Anyway, enjoy no more shuddering and annual brake jobs.
