87 Conti makes noise with braking

[TbirdRoy]

I have just gotten an 87 continental Givenchy model. It's a gorgeous car, and only 29000 miles. The only problem is that when I depress the brake pedal, there is a soft noise (like a vibration) that stops when I let up the pedal. Anyone have an idea about this? Thought it might have something to do with air suspension, but should I be able to hear this working from inside the car? ps- the mechanical day/night mirror is a hoot. If activated, is flips the mirror back and forth very quickly. I'm sure people behind me think I am flashing lights at them or something. I just leave it off. Anyone know of a fix for that too? Thanks for any input -

the noise when braking is likely a brake problem. even tho it has only 29k on the clock, the brake parts are original (if they havn't been changed out), and probably due for changing.

as far as the mirror goes, I cant help ya, no experience with em
