If you can't get the pins out then you gotta replace the brackets.
If you can take the pins out, you can clean them up, clear out the bore then slide into and replace the boots (since they most likely have a tear). If you can reinsert the pins and the move freely then you can reuse it.
A new bracket from ford might cost more than these calipers are worth. I bought a PAIR of those PBR's off Ebay for $20. They are becoming dirt cheap.
