I have a '10 F150 Platinum 4x4 (6" lift and 35's), with about 53k miles on it. A month ago I changed the front brakes because they were pretty bad, but didn't change the rears yet because they were still good. I've put over 1000 miles on the truck since I changed the brakes. A few days ago this terrible super loud squeaking started. I can't tell if it's coming from the front or rear. At a slow speed it's crazy loud, as I go faster the squeaking also sounds faster until I reach a higher speed and it stops. It also stops when I apply the brakes (see video). Any idea what this could be? It's so loud it's almost embarrassing, and it surely turns heads.
No, not always. Because when you apply the brake you have an equal clamping force on both sides of the rotor. You would easily be able to find out which wheel it is by jacking the corners up and rolling the wheels by hand.
