ok, figured it out. There's a lil plug on the bottom-rear of the disk that needs to be removed. Inside you'll see a small gear which is used to adjust the parking brake. Take a flathead and turn it so the gear teeth move from bottom to top till it stops. Doing so will retract the parking/e-brake pads enough so that the disks can be pull out. Everything is pretty much straight forward with removing calipers, brackets, and pads. This hickup thing with the e-brake is what took me a few tries.. Actually it added to some 3 hours to what honestly could have taken 10-15 minute for each side.
