Hello, Im wondering if its necessary to replace the caliper brackets? I had a bolt pin stuck in one on the front and one on the back, I took them to a shop and they heated it up to get it out and i think they might have ran a drill bit through it to clean it out. So basically could the heat have damaged them or warped them somehow? Im replacing all the brakes, new rotors, pads, and just have to get the calipers now but not sure if I should buy the ones that come with the brackets or if mine are alright.
