Squealing noise coming from rear that goes away when braking. on 2008 Hyundai Elantra

From the inside of the car it just sounds like really bad squealing, but those outside of the car say it sounds like metal rubbing against metal.

Sound diminishes after driving for a while but comes back after car sits for a while.

Get the brakes checked for wear. Sounds like your brakes are worn out and running on metal.
