Metat to metal noise

Noise happens only one time. When truck sits for about 10 minutes or more when I start moving I will hear a metal to metal rubbing noise it occurs only once and after the wheels have made a complete rotation. It doesn't occur again until stopped and shut off for about 10 minutes. One thing I noticed is if I hold my foot on the brake pedal but still allow the truck to coast forward no noise occurs even after a complete revolution of tires and then as soon as I completely remove my foot from brake pedal the noise will occur right away once foot is removed . Noise will not occur more than once once driving until stopped for 10 minute give or take a few minutes. I believe it's something related to the brakes. Just passed inspection with just needing front pads . No change with new front brakes. Can't tell if noise is coming from front or back. Didn't mention to mechanic before inspection since I thought new brakes would solve so asking board and then will take to mechanic if can't figure out by forum.tia

 

Noises are tough to diagnose over the internet.

Anyway you can take video?
