Brakes moaning when stopping

[GCG]

GMC 2019 - Sierra 1500 X-31 with approx 400 miles and brakes make a moaning sound when trying to stop.  When to dealer and they replaces all 4 disc - said they all had burned marks on disc face.  

Came home and still having the same problem.  Has anyone had this same problem?  If so what was done to resolve?

Thanks

Yup I had it on my 2019 Silverado AFTER they did the re flash for the break wear indicator wonkeyness.

I have the same burn marks on my rotors.  Just took the brakes apart cleaned them up because they were squeaking pretty, and I was hearing that "moan".  It stopped for maybe a week but then started back up.  Gonna have to go to the dealership this week.
