sounds like poss backing plate touching the rotors or a caliper is hanging up,recheck your work
Is it making the SAME screeching noise as it was before you changed the pads? Is it possible that the rotors have a sharp lip along its edge? or....maybe this high pitch noise is coming from the engine bay? if so, check your belt and belt tensioner.
Same problem on our 2009 Rogue. I bled the brakes and everything has been great since then. A tiny bit of air in the caliper can cause it. As the wheels get hot from braking, the air expands and slightly activates the brakes, making the problems worse.
Is it front disc and rear drum brakes ? Otherwise you have 8 pads 2 each wheel , just curious , and yes re-check your work.Brakes can be a life-saver!
