Do you think the calipers are failing to release properly? If so, you will not be able to move the car by hand. Open the caliper bleeder screws to see if they release. If that works, look for metal brackets crimped around the middle of the rubber brake hoses. If you have that style, open the crimped part up a little with a large channel lock pliers. Rust builds up inside that crimp and constricts the hose.

You can also crack open the steel lines at the master cylinder. If that works to release the brakes, suspect brake fluid contamination. In the case we'll have to talk further.
