broken bleeder valve!!

I have bled old brakes using the brake line, if necessary.
As for $11.99 brake cylinders, if it says china run.
Used them on my 8.75 when I put it in 5 years ago, set in the garage for the last 2 years non use.
Rear wheel cylinder started leaking down the backing plate.
Took the drum off yesterday, the rubber deteriorated around the metal, letting the brake fluid come out.
Ordered $35 wagner, which will not be in until Wednesday.........
