Permanent roar at the Brakebooster

[biker89]

Hello,
i´ve a 73 Centurion Convertible. I need your help for this problem:
I have a permanent or constant roar from my booster. A leak, I can not find, and the braking force is absolut ok. Even the pedal pressure is in order. The noise is quieter when I brake. What can that be?
Does i need a new brakebooster or give´s a stuff to seal e leak?

Thanks for your help and greetings from germany:beers:

I had a hissing coming from my brake booster a few years ago, and found out that the problem was a vacuum leak inside the booster itself. It was replaced and everything was fine. Although I never had a problem with the braking, I could hear it making noise.

Thanks Adam for your quick answer,
that was my opinion too, to change the booster. Now i have to look for such a part in germany. At last i will find it in the US.

Thanks a lot Adam
