What is the best way to store a fl350 master cylinder so the seals don't go bad ?

Completely dry would be my guess ?

Filled with brake fluid and sealed.

Dry will cause the seals to eventually dry out unless they are in a sealed package.

not dry... that's the worst way... the bore will rust.

brake fluid and that oily type paper, and a zip lock baggie is the way I would go

The bore is aluminum.

LOL
TOOK U LONG ENOUGH

well Ill tell you what not to use, liquid wrench or wd40 to break up some brake fluid green bits.

I was not thinking and used a bit to flush it then noticed 2 days later the rubber warped and I blew my seals
witch means I have to rebuild the hole dam thing.

hopefully kits are still available.

only use brake fluid on them.

I'm getting slow in my old age!
