I am at a lost, I tool my 2006 Quest to be serviced for oil and rotate tires. While I was there I told the tech that I had been hearing a rubbing noice from the rear right side of van. I asked them to please check the van while the have the tires off and on the lift. They told me that my rear brakes were gone and the rubbing noise was from them hitting the sensor. So I had them change my rear brakes. I probably needed to have them changed with 66K+ miles on the vehicle. Now I have new brakes but still have the noise. Anyone got any ideas?Thanks!

Is it a rubbing, or more of a metal scraping? I've seen instances where the "protector" on back of the hub was pulled in a little too much and was scraping the rotor.
