I just tore into my rear brakes to check out the problem and to eliminate the confusion, Jeeplibby, they are rear disc brakes with a smaller drum brake under the "hat" of the rotor, so there are two separate brakes on the rear, Discs for primary stopping and a smaller brake shoes just for the parking brake.
I had a friend engaging and disengaging my parking brake from inside the jeep and it looks as though the parking brake does not disengage. This is evident by the fact that there is no more brake material left on the shoes, and it is down to the metal, which was constantly making contact(which explains my terrible gas mileage, and the noise coming from the brakes.) with the rotor.
Has anyone had this problem, it seems to be way more complex then just changing out the parking brake shoes, since the brakes do not disengage.
