Narrative:
On a training flight with my instructor we were preforming a short field takeoff. This was my first flight in a multiengine plane after six hours in the simulator. With my feet on the brakes I applied full power and then released the brakes. We rolled forward about a foot before the plane made a sharp yaw to the left and stopped. I reduced power. The brakes were locked up. At this point we did a positive exchange of controls and my instructor took over since he was PIC. He called the tower to alert them to our aborted takeoff. We checked the parking brake but that wasn't the problem. He called the tower to let him know that we were going to shut down and need to be towed to the ramp. Suddenly the brakes unlocked and we were able to taxi back to the ramp.
