same here
it sounds like you are machining the rotor. and it's from the rear wheels of the car.

its not from the back, its from the front....
took the wheel off and the sound got worse....

it doesnt even sound like its scraping or grinding!

heres a vid of what it sounds like....

when i did all of these tests i still got nothing. i ended up changing the bearings after doing a risky thing which i will not recommend. i chocked my car in place raised one wheel ,of the ground took off the tyre and ran the car no more than 60km/h without the wheel on that side. when i heard the noise it was definitely coming from the bearing area...

and yes there are bearings in the rear wheels as well...

hope this helps..

from the other topic but got a really weird feeling that it may be the bearing....

It's probably your brake pads. If they are going metal to metal, then they will get louder as you slow down. They are a piece of cake to replace. You can also check the thickness of the pad while the wheel is off.

If the brake pads are okay, grab the disk with your hands (make sure it i cool) then move back and fourth to check any movement between the whole disk assembly, and the hub. This will tell you if you have a bad bearing.

Then check and make sure the bottom of the dust cover isn't grinding against the rotor.
