It's a good idea to get a repair manual if your going to work on your own vehicle, and it's never been easier or less expensive to get a high quality manual.

Read up on the job you are about to perform, it will show you what special tools you will need and you will be much better prepared to tackle any job on your vehicle.
Early on, it was a warranty issue, as ford used contaminated pads which would deteriorate rather quickly. I had new rotors and new pads installed free of charge, but for whatever reason they do not last more than about 25,000 miles. I am on my third set of rear pads, the front end is just now giving me indication that they need attention at 80,000 miles. Why the rear brakes do not last is beyond me, as the rear should only cover about 30% of total braking. I remember the days when brakes were done about every 20,000 miles, depending on how they were used and or abused, so at 80,000 miles on original set of front pads is a plus.
Oh, even after getting the proper tool to back out the caliper on the rear to replace the pads, it was a pain....I did one side and called it quits and had the dealership do it, which was cheaper to do than I had thought.
