Were both rotors/calipers hot ? Has anyone been adjusting the master cylinder stop screw ? If so you will have to back it out until it does NOT touch the piston ., This keeps it from being a hydraulic jack . If this is ok go to the next step .
You will have to get the front wheel off the ground and spin the front wheel and apply the front brake . The front wheel should stop and when you release the brake lever it will be free to roll.
If the wheel does not spin break one caliper bleed screw loose and see if it spins .If not try the other side . This test will prove whether or not the problem is in the caliper(s) or not . If they do not release , it is the caliper(s). Remove them one at a time to see which one is sticking.
If they are not at fault , the next step is the brake hose or master cylinder. Pull the front brake lever 3 Xs and release . If the brakes hold , loosen the bolt holding the banjo fitting to the master cylinder . If the brakes release , the problem is "probably" the brake hose .
Don't forget brake fluid & painted surfaces do not mix .
