I have to applaud Ford on this one... Finally replaced my brakes and changed my rotors. These were originals, I ended up getting 71,000 miles on them. I had wear sensors on 3 wheels - the front passenger side did not, and that was the wheel that started making horrible screaching sounds about 2 weeks before I changed them (pads and rotors had already been ordered at this point). All the pads still had some wear left to them - 1/8" to 1/4" on all except the inside pad on that front passenger side which was completely gone. There's really not much of a difference in stopping except for no horrible screaching. Almost got new Ford rotors and pads (not Motorcraft, which according to the Latham Ford parts department is Ford's "value line") but decided to go with less expensive ones.
