I put new rotors and pads on the front of my '97 Grand Marquis about 2,000 miles ago. What a difference; no vibration and stops smooth and fast. The ceramic pads are quiet and dust-free. I'm going to go with ceramics on my wife's 2003 Expedition as well in hopes of reducing the ridiculous levels of brake dust the factory pads produce.
Also saw a site with good DIY instructions for the rotor/pad job...

It's an easy job for most wrench-turners but it's still nice to have some detailed instructions (and pictures) specific to our cars.
