Is my brake booster bad?
I just read some scary threads on the brake booster failing in the GSs and now I am very concerned... Occasionally when I hit the brakes after driving for a while, the booster gives me 'bzzzzzzzz-tick' and it only last for about 5 seconds. To me, it just sounds like it's rebuilding pressure in the brakes. It stops fine, the ABS engages fine (lots of snow driving), and everything feels 100%. My question is, if the brake booster was a-ok, would I not hear this buzz? It is not loud at all, but audible.
Thanks in advance,
Kyle

I made a video. It will do it every time I give two, full, to-the-floor pumps. Still hardly audible from the cabin.
EDIT: Also, I am most scared the unit will fail suddenly as someones did recently. Is there any signs I can search for before it fails besides the obvious?

Mine used to buzz only and now it makes a squealing sound after the buzz.
Looking to replace mine with an 01 or newer unit. https://www.clublexus.com/forums/sus...-question.html
