There is a rubber seal that fits over the rod that pushes the master cly.and and fills the recess in the booster,Is that missing? Noticed fresh paint on the booster and i'm wondering if its pinched or fell out?

If you go the rebuilt/new booster don't be surprised if the master cylinder comes with it .Some re-builders won't sell one with out the other
