My rear brakes make a TERRIABLE screeching sound when I apply anything more than very light pressure. I have tried to wipe down the rim and the surface of the brakes think that something is in between the two but it hasn't solved it. Any suggestions?

Toe-in
One glitch that affects some brakes and can drive you bonkers (and guarantee that you never see any wildlife) is squeaking. To prevent this, there’s a brake pad adjustment called “toe-in.” It involves slightly angling the leading edges of the pads in to touch the rim first.

Thanks. I'll try it out and see if it works.

and if that doesn't work, check to make sure there aren't any small animals trapped in the caliper

Check to see there isn't some debris stuck on the brake pad.  Also, when you clean the rim-use 90% rubbing alcohol (vs. the 70% 'rubbing' alcohol).  If the pads are old. use a fine woodworking rasp to scuff up the pad where it contacts the rim.   

Oh, and check the toe in....

Thanks all for the advice. I have the cartridge type brake pads so the toe in problem would only be solved if I bought brand new pads and these pads still look like they have a lot of life still in them. I tried cleaning the rim and the pad with alcohol but the screeching sound was still there. I had an idea to just swap the front and rear brake pads to narrow down the problem and there is no screeching now and the brakes work fine. If anybody knows if swapping the pads is a no-no then please let me know!

On a different question how often do you replace your brake pads?
