I just replaced both my front brake pads and it took all of 1 hour. One step that was left off the above lists, was to drive out the pins that hold the metal clips in place. I use a pick and hammer and gently tap them out. The toughest part of any disk brake job is pushing the caliper cylinders back far enough to fit in the new ones. As you will see your old pads are very thin compared to the nice new ones. If you try to push in the new ones they won't fit until you push those pistons back. I use a piece of wood and a large screw driver. Sometimes a good pair of pliers can "squeeze" them down. While your in there I would also replace your brake fluid with ATE Racing Blue. A messy job but well worth it. Remember old brake fluid attracks water and will corrode brake components like caliper pistons. I have warped more than one rotor disk like this. I use the Ferodo pads and highly recommend them. They are truly awesome. You CAN do this!
Good luck!!!
