squeaking noise at low speeds

I just bought a used 2000 Subaru Outback and I have started noticing a
'squeaking sound' when I am moving in first and second gears. I am not
sure if the sound dissapears after that or I just dont hear it over the
wind (since I have my windows down to try and hear the sound). I am
going to take it to a mechanic next week but I'd like to have some idea
about what it is so I dont get ripped off.

The front brake pads are at 5% and need to be replaced. Could that be
the problem?

Could they be springs on the fly wheel?

I would greatly appreciate any input on this problem
