Go all the way up to the hydraulic controller and crack open the lines to see if the brakes release. If they do, I suspect this might be one for the dealer. Unlike some older systems, there is no brake fluid stored at high pressure so leakage in a valve shouldn't be a problem, however, I suppose a valve could be blocked and not allowing the fluid to go back to the master cylinder.
The base hydraulic system is still a split-diagonal design with the two front brakes on different circuits. They each also have their own circuits during an ABS stop. That would imply there would have to be two blocked passages in the controller or a blocked passage that is common to both front wheels. That's assuming, of course, that both front brakes are locking.
This isn't something I've run into before. I hope I'm wrong about it needing a controller.
