Sorry, I missed your reply.
When these units have been dry for so long, the only option is to repair or replace the master cylinder. If it were moving so fluid, I would say you had a plugged line or fitting/check valve in the end of the cylinder.
The main issue for one that has been dry for a long time is corrosion. The bore will be pitted and polishing may not clean the bore. If it is not perfectly smooth, it will destroy the new seals.
I usually replace the whole unit but, that is because our company policy is to not allow an chance for a failure when working on brakes. SAFETY FIRST!
If you need more help on this, please feel free to ask. I will be glad to help as much as I can.
