Have you tried loosening the lines at the valve, or at the caliper to releave pressure? You may have locked calipers.

Did you happen to change the master cyl and booster when doing this project?

When you say they do not release, do you mean after you press on the brake pedal the wheels do not spin with both front wheels off the ground?

Is it possible your transfer case is in 4x4 and your front drive shaft is jammed against a cross member?
