There is a special tool needed to back in the self-adjuster nut in the center of the wheel hub assembly. This nut has to be backed in so that you can slide open the caliper sufficiently to be able to remove the old brake pads and install new ones. The nut is embossed with a shape like an hour glass (as opposed to, say, a Phillips or slot shape). The tool will snap into a 3/8" socket driver and with this, will then fit into the grooves to permit you to turn and back in the nut. In Canada, I found a multi-tool that did the job at PartSource. It was under $10. Ask at any reputable auto parts supplier - they should have it. (Note: If you take your time and are patient, you can also use a pair of needle-nose pliers--open them slightly and put them on either side of the narrow part of the hour glass and slowly twist counter-clockwise to release the piston. You have to turn it several full rotations, so be patient)
