Default power brake booster

My 88 vette has a vaccum noise down around the brake pedal. Could this be a bad brake power booster and is there anyway to check it?

If the noise changes when you step on the brakes or the brakes require more effort, then you have a bad booster.

Hearing a whoosh and having to shove down the brake pedal is a definite sign.

I agree with the above posters. I had a hissing sound whenever I pressed my brake pedal so I changed the booster and it was resolved. Also, if at a stop my pedal would be about half-way depressed and then sink to the floor with almost no change in pedal force.
