Hello. I a new here but was wondering if you could help me out with a problem I am having. I just changed the brake pads and brake rotors and now I get this obnoxious noise from what I believe to be the brake rotor hitting the brake pad. When I spin the wheel by hand I can here them rubbing but it gets incredibly loud when I start driving. Around 20mph it is at it's loudest. Any advice on what to look at to fix this problem?

Thanks!
