Brakes "creek" when pushed down (slow or stopped), read, wondering if anyone knows, little hard to explain Options

[mgnt232]

So i recently noticed this odd noise my "brakes" make (imagine it is the brake since it only happens when they are depressed )
It is only when I am parked (starting my car I press it in to take off the ebrake and can hear it) or like rolling to a stop sign at 5mph (or at least this is when i can hear it).

When the pedal is depressed, it goes down a slight bit, and then starts to feel harder as i push further. After the initial push when it gets hard, if i push slightly past that (only when im coming to a complete stop, or taking the ebrake off. I never push the brake further any other time) The front brakes kind of creek (sounds like it comes from the front).
I can only explain it as like an eerie sound of a creeky door

Braking is not any different since it started (at least nothing major)

I was wondering if this is a sign of the caliper going? I replaced the pads and rotors when i got the car, but not the calipers, and I imagine the condition everything else on my car was, that they are pretty old.
Its an odd sound, hard to explain, maybe ill get a video

I got my brakes all around replaced (front rotors/pads, rear drums/shoes) not even 150 mi ago and they still do it sometimes. I don't think it's anything. I mean, new brakes, c'mon. Haha
