Are you replacing the caliper or just the pads? My advice, for what it's worth, replace both sides. Once you have the caliper off, you should be able to see the letters ATE in cursive on the half closest to center of car. If not, thne they are bendix. For safety and peace of mind, I replaced all my calipers, rotors, pads, all four for $550. autopartsgiant.com It doesn't matter what you have now as long as you replace both sides similar.
