Quick grinding noise when releasing brake from complete stop?

Not sure if this is normal, but often times when I release the brake from a complete stop, especially from downhill positions, I hear a pretty obvious although short grinding noise right as it is released. Not sure how long it's been happening, but it got a little annoying today while I was stuck in the traffic on a downhill slope having to stop and go multiple times. Ever since it annoyed me once it has become more noticeable.. (amazing how our genius brain works). Have you guys have had this issue before? Is it worth bringing to the service center for a look?
 
Off the cuff it sounds like the typical sounds I've heard on my new Tesla at low speeds and on all of my previous cars. Not sure if it's the ABS system or just nuances of the brake pad + disk. Is it more of a pulsing sound? My driveway is very steep, so I notice this when I come off the brake going downhill, but usually only when rolling at slow speed.

Question though - when you release the brake, doesn't hill hold keep you in place? I only notice it when creeping at very low speed while maintaining light pressure on the brakes. Not sure if it's the same thing I hear from time to time, but it's always seemed like normal braking sounds to me.

If it's truly a grinding sound then that could be something else.
 
I've also noticed a louder sound than I'm used to in other cars, mostly when waiting uphill on the driveway while the garage door closes and when I release to then continue backing out. I wouldn't categorize it as grinding but more as deep squeaking/squealing sound. Not pleasant, for sure. I wondered if I should hose off the brakes as I do with my other cars? Just didn't figure there'd be that much dust given use of regen, but the car is new and maybe that's affecting it early on?

Could it just be the brake booster pump?
