I was changing the brake pads on a 97 Nissan Sentra and the sliders on the caliper brackets were frozen. I tried to take those out, but accidentally drilled a hole into the side of bracket. I purchased a new bracket from autozone and it was .3 inches too big causing the brakes to sit too high and preventing the wheel from going on. I went to napa, and their part gave the same problem. Has anyone else had this problem? The bolts are 17mm on the bracket I have, but for some reason the other ones seem to be larger threaded holes. What could be going on?
