For Sale: Rear Cadillac calipers, with brackets for brake upgrade. (Page 1/1) RotrexFiero FEB 12, 07:26 PM I have two rear calipers from a cadillac, along with the custom metal brackets, to upgrade the Fiero rear brakes. I have all the hardware also. They are in good condition. Please make an offer, remember shipping. This upgrade allowed for a larger disc, and also maintain the rear brake. They have never been installed. Let me know if you are interested.
