Rear brake sound when stopping in reverse
 

Gents,

I am having an interesting sound coming from my rear brakes when I stop from reversing, for example, when I'm pulling out the drive way or a parking space. It kind of sounds like a loud "hum" that lasts a spit second, until the car actually stops.

I changed the rear brakes and rotors about 1500 miles ago.
