Brake Calipers + Screaching Wheel

[lingerlonger82]

I went to the usual shop to get my explorer checked out yesterday because my front driver-side wheel was making a horrible screaching noise when driving. The sound stops when I brake. They said it was my brake caliper and it needs to be replaced. - - - $100.00 part!!!!
Later that day, I noticed and listened hard when I stuck my head out of the window, yo, the sound is coming from my rear driver-side not the front driver-side!
I was wondering if anyone might have any clues of what it is, just for a second opinion and I will probably take it in elsewhere to get looked at, for another opinion. Plus is there anywhere I can get cheaper parts?
