I have not driven my e420 in at least 3 months or so. Anyway, this week I decided to drive it. I stop at a friends house and applied the parking brakes. About a hour or so later I release the parking brakes to leave and they would not release. The brakes were stuck. I got up under the car and checked the parking brake cable to see if it was broken but everything was okay. I unscrewed the adjustment cable to allow the cable to have slack and still no change. The parking brakes would not release. I stuck a screw driver into the lug nut hole and tried to adjust the lever that push the brake shoes to the rotor and still the same results, no change.

After dealing with all of that I decided to remove the brake disc rotor, but I was unsuccessful. Can anybody tell me what is up with the parking brakes and if I am missing something on getting these rear rotors off the car.
