dabangsta Posted June 25 Report Share Posted June 25 At around 87,000 miles on my 2019 FWD SEL, and the rear pads are getting pretty thin. I have not had a car in recent memory that I didn't do some sort of big brake upgrade to (10.8 inch to 13 inch Cobra on my Mark VIII, 14 inch GT500 on my Grand Marquis, etc). Mine is FWD and has the smaller front rotors (316mm), and I want to go with the 345mm AWD ones (not looking to go with the ST Base or PP). I will leave the rears the standard 316mm solid. It seems like the caliper is the same for either rotor (and pads), just the bracket/support/mount is different. Can I just go with new caliper mounts, rotors, and pads from the AWD? Or do I need the bracket and caliper? If I put in the VIN for my FWD and for an AWD vehicle, I get same PN for calipers, different for rotors and brackets(supports), so not sure. Also they are referenced as "front vented 17" and 18 front vented. I assume that is for older years that still had 17 inch wheels standard (but all 2015+ have 18+ wheels). If I can get away with not unhooking the calipers so I need to bleed them, all the better. I am going to guess that it won't affect anything like ABS, stop and go cruise, collision avoidance, etc. I have a 17 inch spare, I think I have seen recent posts about 17 inch spare fitting over front and rear ST brakes, which have same rotor size but caliper is different.

dabangsta Posted June 25 Author Report Share Posted June 25 I haven't checked the thickness of the rotors, but I haven't had rotors turned in a long time, and I don't plan on pad slapping this one either, so $100 for the caliper brackets, and slightly higher for the bigger rotors but not major.
