I understand that there is a certain way to glue the brake pads to the metal pads. If you glue it wrong it will cause serious binding.

2) make sure that the disc is seated straight on the three prong attached to the pulley. in time it will loosen up but for now check by rotating the shaft or rear wheel .look at it while rotating and you will see if you have a bind. if you have one try to move it around by a screwdriver against the pulley and twist gently until it is smooth.
3) please make sure that your brake post is not reversed. I meant that the flat side is facing the metal of the pads. good luck!!!! enjoy...

4. There is a top and a bottom for the brake plates. If this isn't correct, the brake plates will bind.
5. Make sure the holes in the brake plate/pad assembly are free from glue. I open up these holes so they slide easily on the pins.
6. Most likely you have used too much glue to adhere the pads to the plates. There is only so much room between the brake post and the stops. Sand down the pad material until each pad/plate is approximately 2.1 mm and make sure they are flat and parallel.

Seems like everyone is pointing you in the right direction. The issue with the pads having a top and bottom is something to check, I know because I have assembled the rear end on my MRX4 many times. I would not sand the pads to much after assembly because if you run the car you want the pads to seat properly. The pads should only slightly touch the disc with some play until engaged. Sounds like you need to check your rear end/brake assembling.
