97 Cutlass Supreme: Squeeks when not braking

Got a 97 Olds Cutlass Supreme that Squeeks (high pitched, rubbing) when go at slower speeds >20 or in reverse, and stops when I apply the brakes. The squeeking is coming from the rear. Had it checked at Midas, and they didnt see any brake problems. Any ideas???? Thanks!

I'm thinking you may have a bad wheel berring.

maybe a wheel bearing, or possibly just break dust, try hosing the wheels and brakes down and see if that solves your problems.
