ive had a frozen rear caliper recently and a semi frozen one on other rear side now. im not even dealing with it now because its my 4th frozen caliper in 1.5 years of ownership. ill let it burn up before doing another in the next few mos or so.
What calipers have you been replacing it with, so i can avoid those. I joke, but man, that seems way out of line. I'm sure the salty roads play a role in that, something i don't have to deal with.
