The caliper bolts are 13 mm, so use a socket or wrench, if not too tight. a "C" clamp works well to push the caliper piston back into the caliper housing. That's it, change the pads and put back together. Also, best to use some brake cleaner to clean the old brake pad dust from the caliper and rotor, and should use some lub on the new pads at all points that contact the caliper. Have the rotor turned if they seem to be scored, if not don't turn them. Turning the rotors will thin the surface, making them more prone to heat warping.

Lug wrench, metric socket set, "C" clamp
It is mounted on a bracket under the dash at the brake pedal. From there it is self explanatory.
Only take apart one wheel at a time so that you will have the other wheel to use for comparison. A few basic inexpensive brake tools would be helpful. Ask your local auto parts store to help you with the tools needed.
