Have you checked to make sure the brake springs are not broken or there isn't something out of place that can be causing a rubbing?

Yes I have pulled off both rear tires and taken the calipers, pads and rotors and inspected everything and cleaned and adjusted everything also. Still "mooing" or moaning.

If the noise is from the rear, then it must be in the differential or an axle bearing. Check for problems there.

It isn't the rear diff I know that. It is in the rear brakes. I am just not sure whether it is a "sticking" caliper, pads, rotors, e brake or what.

If you checked it, I don't know what to say. My first guess would be the poorly designed park brake.

Actually the parking brake is fine. I believe it has to do with the caliper on the rear drivers side.

I don't know for sure that it is sticking but everything else is good. I am pretty sure it is the caliper.
