After owning 6 fords (64, 72, 88, 93, 02, 08) bought used or as project cars, etc., every braking system is different! I'm not a tech or Ford employee or anything, but it's definitely time for a trip to the dealer. The dealer who replaced the rotors on the original thread starter here did he/she a HUGE favor. Remember dealers are independent businessmen and can make the case to Ford to pay for replacement parts under warranty that will avoid issues from "reappearing" down the road. If there is a TSB on rotors, REPLACE THEM NOW. Turning rotors for a "pulse" or even more severe "clunking" sounds drastic, but turning/machining rotors just means the pulse or clunking will come back w/in 10K miles in my experiences. It's really not that complex to replace pads & rotors folks and replacing parts is cheaper than 2 or 3 visits worth of labor. Give that service manager and the tech who does the job a gift card for looking after you if you get treated this well. You will be rewarded the next time you come back for something that's marginally under warranty, I promise. ;-)
