No brake fluid to front brakes.

Good evening everyone! Just going g to bleed brakes on the tuna can and ran into an issue.. I have no brake fluid getting to the front wheel cylinders. Wheel ends are all new including wheel cylinders, shoes, drums, etc. Every single brake line and hose has been replaced as well. Only thing original is the master cylinder and junction block. The master did leak whe. I bled it (sat for 3 years dry), I took it apart cleaned out the gunk and reassembled. Seems OK now but.... any thought from the great minds in this forum? Could it be the junction valve? I cleaned and blew it out before reinstalling.. again everything is new. Pedal feels solid with 2 pumps. Back brakes are good... getting cranky in Toon town
