If the one I have is that way how would I know? The body won’t pull all the way apart when you split it? Or is there another way to tell

How can you tell which seals are junk just by sight or just replace everything once you get in there?

Awesome I will definitely be doing that when I do the booster!

Oh awesome I didn’t even know they made a seal kit I just figured it was a throwaway part honestly. Thank you very much!

Brand new here hoping to get some advice. I noticed my drivers side front fender liner was getting oily the other morning and traced it back to the brake booster. I would like to replace both the hydro unit and master cylinder at the same time is this advantageous or should I not really worry about the master as it has no signs of leaking. Truck has 380k on it as it sits. Also any tips on changing one or both items would be greatly appreciated thank you in advance!
