I'm beginning to think that pebbles are getting into the parking brake drum area as opposed to merely the rotor/shield area. They would be putting pressure on the parking shoes and moving them around. I can see how greasing the springs would help quiet the noise, but really not solve the problem.

Thing is, I have never disassembled that part of the car. For those of you that have, is this a viable theory?
