Well, it's not the calipers or master cylinder since fluid pumps out of the brake hose connection when loosened, and calipers are fine. The issue is that the ABS modulator is blocking fluid travel to the front hydraulic circuit as there is no fluid coming out of the bleeder screws. Forcing the lever and attempting to make the ABS pump run finally freed things up and I managed to get a whole liter of Castrol Dot 4 cycled through the system and bled. Brakes working fine now, but hesitant to ride in traffic until I am 100% sure this won't happen again.
