First off, the parking brake is a completely seperate system from the service brakes. The parking brake consists of 2 seperate drum brakes inside the rear rotors that are cable operated. Using the parking brakes will have nothing to do with warping rotors, I have no idea how someone could come up with a conclusion like that.

Second, the park mode in the tranny uses a parking pawl to engage a "window" which mechanically locks the output shaft of the tranny to the case of the transmission. I have never heard of it "wearing out." If you park on a steep hill, it is adviseable to use the parking brake in addition to the park mode on the transmission.

On your issue, either the parking brake cable has stretched and needs a readjustment or someone did some excessive driving with the parking brake on and wore out the parking brake shoes inside the rear drums.
