    When you say not moving, do you mean it is completely frozen in place? As in, even if you removed it from the car, you couldn't press it in or blow it out at all? Or is the fluid just not compressing the piston to apply braking force?

    If it is the latter, have you bled the master cylinder? Do that first, and then bleed the caliper.

    If it's the former, sounds like you may have gotten 2 bad calipers.

    Possibly a little more damage like a hard line crushed?

    I was thinking damaged brake line as well. Check the hard lines and whenever I replace a caliper, I like to change the rubber lines leading up to them as well. Sometimes the rubber lines can actually fray on the inside and the piece of frayed rubber acts as a flap or one way valve letting the fluid go one way but not the other.
