Welcome aboard. Do you have the brakes adjusted up properly in the back? Is it plumbed correctly from the distribution block?

Rear axle soft hose? Might be collapsed?
Might be dirt somewhere in the line to the back? Disconnect at the Wheel cylinders and the front junction and blow air back through, maybe?

were they working before? or have ever had them working? because if they were and then stopped (no pun intended lol) working, you must have either lost fluid or something is obstructing the flow of fluid OR you sucked air into the lines, just a thought....
