Thanks guys!
I have noticed that at times turning to the left will cause the screech to become a little louder. I understand that this may in fact not be the brakes, however when I isolated the screech, it was right on the wheel. The CV joint is in the center of the rear axle, isn't it? The screech still disappears for a while after a wash though. The screech goes away, or is at least minimized, after 25-30 mph. And it is louder when the car is moving slowly.
Thanks again for your help. I'll look at it more closely tomorrow and see if the screech is maybe not coming from the wheel afterall.
