If you have never done this before I would recommend having a technician replace your pads. The brakes are a safety item and if there is a problem with the caliper or the piston and you don't see it, it could be dangerous.
Usually you would use a giant C-Clamp and the old pad to push the piston back into the caliper. Again, there is more to it than this simple explanation, so please don't do this job yourself if you are unfamiliar with these tools. Best of luck.
