My suggestion: Buy a brake cylinder hone and pull apart both rear cylinders and 
hone them in place. Clean up the innards and reinstall them; they are 98% 
likely to work just fine. The problem is almost always rust in the bore which 
you will hone out. Brake fluid makes a very good honing fluid, too, but wipe 
out the residue before you put things back together.

Doing this is easier, faster, and cheaper than replacement, and it lasts just 
as long. It has the added benefit of taking NO chance of twisting off the steel 
brake line when you try to turn the line nut.

And, yes, I would do both sides while you've got it jacked up..

Remember that if you don't use silicone brake fluid you should flush fresh DoT-
3 thru your system every 2-3 years or you'll have trouble like this due to 
internal corrosion.
