    I have a 1995 gmc 3500 The brake booster is leaking into the cab and I have never had one of these apart. It also is leaking on to the firewall. Question is can it just be a seal or gasket to replace or does the booter need replaced? Also could the master be leaking into the booter? Meaning is the master bad? Brakes work fine. But now it leaked in the brake switch and the brake lights are stuck on. ANY HELP WOULD B GREAT!

    they are not rebuildable!!!!!!!!! only part that you can change is the push rod
    you might not need the master, just the booster

    I would do both of them. You'll have very little extra cost involved plus you are that far already.! Be prepared for that booster cost. Just did mine a couple months ago and was around 375 for both units.
