When i release the brake peddle the brakes on the back (drums) make a squeaking sound. What is it? I cant figure out what it is. The Drum and pads are still in good shape.

 

I would have to say two words; Clean and lubricate.
It sounds like the shoes are not fully releasing. This can be caused by a number of (usually) simple-to-fix issues and it all involves basic maintenance.

 

If the drums and pads are still in good shape it might be that your hand brake cable is not releasing all the way. Go under and visually inspect the cable connection near the rear diff. There are 3 cables that interconnect, one each from the rear wheels and one from the lever. It could be that the plastic that wraps around the cable is cracked exposing the wire and that's where the moisture will come in causing the wire to rust overtime. I changed two of the cables on my 01 Tribute for that reason.
