Rear brake noise

This last summer I noticed my rear brakes becoming squeaky noisy when applying. When driving in town very noticeable at stop signs, like I had a bad stomach :( I have winter to take a look at it now. What am I looking for? loose cable, something come apart in there, is this a common thing after a few thousand miles?
