Front brake vibration
I have an F-150 Screw Lariat 2004. I bought it new -- all still bone stock.
After several thousand miles the front brakes started vibrating, particularly if I was braking only slightly. If I really pressed the brake pedal for full stop from highway speed the vibration didn't feel so bad.
I turned the rotors and the vibration disappeared. Now again after several thousand miles the the vibration is back.
Do you have this as well? Is there a Ford Technical Bulletin for this?
I appreciate your experience/comments.
And a very HAPPY 2008 to you all and your families!

since you had them turned once already, i would measure them to make sure they are still above the minimum thickness. also check your caliper slide pins to make sure that they are moving freely and not sticking.

I put new front rotors on my 04 (got them at Napa) and after just 10k miles they were warped. Had them turned but I am sure it will come back. The stock rotors never warped. I would also appreciate anyones input.

Wolf; It's time for new rotors. Rotors and drums are service items and are not intended to last the life of the vehicle. 25,000 miles used to be recommended as the service interval (replacement) for rotors. If you have a place you can safely do this, try a panic stop from 60 mph, without locking the brakes or activating ABS. Hold the pressure until the truck stops - don't let up for an easy stop. Frequently, the rotors will be sufficiently cleaned to reduce or eliminate pulsation for awhile. I did not believe the guys who were saying the rotors don't actually warp, they develop uneven build-up which grabs as you stop. After actually doing such a stop at a red light one day, the pulsation in the brakes of my SUV was significantly reduced. It's probably good to do one of these stops every month. Sooner or later, though, the rotors will be worn too thin to keep. 50,000 miles is probably the extreme upper limit for stock rotors.

My F150 just turned 14K miles and I've had a slight vibration for a little over 1000 miles. I asked a friend who is a Ford Mechanic and he said the rotors on these trucks tend to need replacing at fairly short intervals. Luckily mine will probably get replaced under warranty but as soon as I don't have the warranty option I will slap on a good quality aftermarket rotor.
