    Rear Mustang Cobra Caliper Gurus

    I have a used set of rear calipers and brackets I am going to try and sell on Craigslist. The receipt states they are for 1994-1998 Mustang Cobra, part #18B4544A and 18B4545A. I thought the rear calipers for 1994-2004 were the same?

    Looking at RockAuto.com they have separate caliper/bracket part numbers for:
    1994-1998 - Part # 18B4544A and 18B4545A
    2001-2004 - Part # 18B4824A and 18B4825A

    Looking at the Specs. and Pics. they look the same to me. What is the difference between calipers on those years?

    I bought some new powder coated calipers for a 2001 Mustang Cobra from PowerStop part number S4824A. They looked exactly like the ones I took off(except for the Ford logo cast) and they bolted right up.

    Front calipers 94-98 had smaller pistons than 99-04, and the lettering was inset in a rectangle rather than raised letters.  I have never been aware of any differences between any years on the 94-04 rear cobra calipers. There was one year that had red calipers and they used different threads on the banjo bolts than the grey ones.  Go figure…

    I have been finding that it's really hard to tell the difference between 10mm x 1.0 and 3/8" x 24

    10mm x 1.0 is .0394”pitch,  3/8 “ x 24 is .0416 pitch .
    10mm is .393 diameter compared to .375” for 3/8” x 24.
    You can start a 3/8” into 10mm  a few turns but will bind as it advances.
    A 10mm bolt might be tighter to start depending on thread class of either component.
