Prob for a rear? I did notice on eBay that the newer caliper were single pot and the older ones (pre 2015) were dual, so maybe someone screwed up the cross over P/N's cause i cant see them going down to a single pot caliper on a turbo'd larger SUV.Well, got the part today. The part number on the box was correct, the part inside wasn't.....I don't know what it is for but it isn't the right part. Its tiny, smaller than the Mazda 3 caliper bracket. The mounting bolt hole centers are more than 2" too close. It doesn't look anything like a CX-9 caliper bracket..... ?
