So as I become more acquainted with my car I have noticed something odd. My front wheels have virutally no brake dust after 3 weeks without a wash. The back passenger wheel is black (literally black), and the back driver wheel has a slight dusting. Now every car I have ever owned has always produced more brake dust up front due to the brake bias (I assume) except this car. Could this brake dust be evidence that my front brakes are not working the way they should and my rear brakes have to work harder to stop the car?
brake question (again)

Yeah, that doesn't seem right. Does the car seem to brake well, or do the brakes seem weak and cause a bit of a pull under braking?
My car has the sport package and the front brakes definitely show more dusting than the rears.

Is it possible that the front and rear pads are made up of different compounds for some odd reason?
The car brakes okay, and that is just an okay, not good, not great. It does pull a tad to the right under moderate braking. When I was testing the brakes I could not get them to lock at 40, and they barely locked at all from 60-0.

My advice would be to wait until you have the same amount of brake dust built up and then take it to the dealer. That way, you can actually show them what is going on rather than them test driving it and finding nothing wrong.
What was the fix?

Don't take my advice.
A stuck caliper, already, perhaps?

It's the way Ford programs their Electronic Brake Distribution. Under light braking the rears do a bunch of the work as it makes it easier to control steering. Nail the brakes and they all work like a traditional system. I believe it's the same way in the Taurus.
Check this thread:

Look at the post by Waldo - he's a Ford engineer and he has some insight into how Ford has it programmed.
I wonder if Performance Pack SHO's have "regular" programming and the rest of us get the EBD programming.

Thanks for the info ITguy!
I have 22k on my SHO and the rear breaks are noticeably more grooved up than the front. I would consider myself a "light" breaker, so this makes sense.

No problem - glad to help. I'm a light breaker as well since I drove stick you learned to let off the gas early so you didn't have to do the foot shuffle. As well as the art of downshifting going down a hill and letting the transmission and engine do the work.
I do throw a hard brake in every once for good measure.

The fix is, as you mentioned, replacing the pads, caliper brackets and bracket bolts with a revised design.

The fix was a letter from Ford explaining the rear pads were stored in an imperfect environment. Premature wear could be expected in which case the letter provided coverage for all costs incurred to all Ford dealers.

Wish I had seen this TSB earlier (my car date applies). My SHO has 26k on it, and the back right brakes were metal to metal a few days ago. As I needed a car, I quickly ordered parts and replaced the rotors and pads that day, thinking this would not be covered under warranty. When I got to the left side the brakes were barely worn. It appears the right side was hanging up ... a symptom of the TSB. I replaced the pads and rotors on both side and then saw this TSB shortly after finishing. I plan on requesting the dealer perform the TSB, as the bracket issue may still exist. Out ~$200 though.
