on my 2006 Chevy Impala LT i changed the brakes about 2 weeks ago and it is constantly makes a squealing noise from the tires when i am moving i checked the brakes and they are fine the rotors are new and the everything is put how it is supposed to i do not understand what it could be if someone has any ideas id thank you if you help. Im not sure if its maybe a hub or the axle thats causing it to do this. Thank You

 

try jacking it up and spinning each wheel by hand and see if you hear anything, might have a rock or something stuck in a pad or possibly bent the dust shield
