Brake Booster 69 GTX

[dhd76]

Hey guys the GTX has been losing some brake fluid and I felt under the brake booster and it was wet, so I assume that is the issue. I did most of my mechanic work when I was a kid and we didn't have a lot of power brakes back then. So I need your advice. I looked through the forum about brake boosters but didn't see information on this problem.
Is the booster bad or is there a seal between it and the Master Cylinder that is leaking? If I put brake fluid in it, the brakes work good.
Thanks guys - again...

If your loosening brake fluid at back of MC you need a new Master cylinder.

The junction from the MC to the Booster is dry. So I guess the fluid is running down into the booster from the MC, correct?

You can, or at least you could, still get a rebuild kit. I was amazed when I pulled mine off Amazon for $32 CANCUK dollars...

Unbolt master without disconnecting brake lines and have a look see.

Wayne did you hone bore of master cylinder?

Brake fluid inside an old booster isn't good for the old diaphragm,I would have the booster rebuilt also.

Hey guys I am back in "fix the GTX"mode. Anybody got a recommendation for a place to get that Master Cylinder? One of you pointed me to Brewers for the transmission parts and they were super good. I hope one of you can point me to a good source with good quality. I'm not saying that price is no object, but I will pay more for good stuff.
