What is this annoying sound from brakes?

[Biking4jesus]

Let's play Name That Sound! I've got a 04 V8 2WD wit 195K. braking action feels fine. pads are good. makes this noise a lot- sometimes when applying the brakes. sometimes while stopped. doesnt occur when not using the brakes.
no codes or lights on the dash.

I couldn't hear any sound, looked for the volume control and didn't see it???

Yeah, couldn't hear it either...

pads "looking ok" doesnt mean anything, my rear pads had almost 1/4" of pad left but the back side pads were worn down to the metal backing plate and were actually digging grooves into the rotors.

pull the rear calipers and check the back side rear pads, i bet you find that was your noise

oh, and as others mentioned, your video has no sound so its useless

Go about 80mph on the highway and hit the brake hard until you get to 40 mph. Then come back here and tell us if the noise is gone. Repeat that 2-3 times.

Did you factory headers crack yet with 195k?

Seeing there's no sound on the video, can you describe it? Front or back? When's the last time the e-brake shoes were looked at? Last time I looked at mine I found many pieces where they shouldn't be on one side.
