I’ve been having this sound for probably about 3 months now. It sounds like the pads are rubbing on the rotor when riding around, I’m thinking it’s either the caliper needs to be replaced because it’s not opening all the way or the front brake lines need to be replaced because they’re original and have probably expanded. The brakes are all brand new calipers, rotors, pads. Any help is greatly appreciated, especially from mrblaine since you’re the expert I would greatly appreciate it.
Brake rubbing sound

Did you replace the caliper?
That's the next step...
Just did my rear truck brakes...swore the noise was coming from front passenger and it was rear.

What I would do is drive around somewhere where you won't have to use the brakes much for 15-20 minutes. If they're dragging enough to hear, they're going to heat up quite a bit.
If you replaced calipers already, then I'd replace hoses — if they're original I'd replace them regardless. They can delaminate internally and cause essentially a check valve so that it acts like a stuck caliper.

Yeah the sound didn’t start until I put all of the new brake parts on so I guess the extra breaking power screwed up the lines
If it is a bad caliper, that would be very odd. I personally hand check each and every caliper that leaves here. I check the bleed screws and holes by unscrewing them and seeing if the seats are good. Then I check to see how easily the guide sleeves move. I check the pistons for any damage. I make sure the dust boot is intact. While they are new, not all of them have been hand built by my favorite brake supplier so I double check everything.
I've yet to find a deficient one from him, so a bad one would be very odd.
The pads do lightly rub on the rotors while driving. Go do the break in again with some enthusiasm and see if that changes anything.

That’s unlikely as the pressure in the hydraulic system didn’t change due to different calipers/rotors.
Did the break in again, still making the noise so I guess it’s time to replace the lines
I had to replace my front hoses last year. They would only pass fluid in one direction, so the brakes couldn't go "off". Now, one of the rear brakes is dragging, so I have to replace those hoses, too. Sort of a pain for an unlimited rubi; there is no separate rubber hose, it is all one piece. Starting tomorrow.
Thankfully(but not) I have drums in the rear so I know those aren’t what’s making the dragging noise
Didn’t see that on the website but no I don’t have those in the rear, I just got power stop stuff in the rear because the rear only does like 20% of the braking power
