[T3] Brake Hose, again...

On advice, I changed the questionable front brake hose with another from one of the parts cars.  Again...and for the 2nd time in my career, all the pedal pumping and pressure could not get a drop of air or fluid out of either bleeder valve....and the wheel turned easily as if brake pedal wasn't doing anything.
   What are chances of the same syndrome happening twice?  Do the hoses automatically go useless after being dry for..well...years?

  Question-   Can a used hose be tested by blowing air through it...or gently using a thin wire?   My third and last hose, and the one I just removed, won't let any air through, and the wire barely goes in at all on both ends.  Should you be able to blow through them?

It's the hose. They deterioriate internally and develop internal 
flaps that tend to block the flow of fluid. Don't be fooled into 
thinking it's all okay. Replace the hose. If one is bad, you might 
want to consider replacing both.

I stock them, but the fronts might be available locally. I have the 
rears also, which you won't find anywhere else.
