I agree.

Same thing you describe happens when the emergency brake is on. Sounds like you still have fluid stuck in the rear hard lines or the emergency brake system is stuck. Rusty cables out back and up front can cause the emergency brakes to stick too so you need to check all the cables as well and not just the parts under the brake drums.

If the rubber hose was clogged then there are probably more areas with buildup in them and the whole system needs flushed out. I fought that on a car I bought and ended up replacing all the hard lines, flex hoses and hydraulic parts in the system to get rid of the contamination.
