Brakes Scrapin' And Squealin'

Hello everybody,
Started my 2000 V6 today to take a 3hr trip. On ignition the car began squealing off and on which sounded just like a fan belt wearing out.

The car has also been making muffled scraping sounds indiscriminately while the car is moving at lower speeds (-20mph).

These two things in conjunction has me wondering if it's more than just break indicators and an old fan belt.

What do y'all think?

Aight, thanks for the help :-D It turned out to be that the brakes were worn out and the front roters needed to be replaced because of that :-(
Also, the squealing hadn't reoccurred but the serpentine belt was old and needed to be replaced anyway.
