Just wanted to post some more info on this in case anyone else has this problem. My 2007 EB 4x2 with 4,000 miles pulls to the left while braking at freeway speeds. The dealer has replaced pads, turned rotors, disabled ABS, etc with no luck. It is at the dealer now and I will keep updating this post as I find out information.
Update: Talked to the service manager at the dealer I have the truck at. We went on a test drive and the car pulled while braking at freeway speeds. He thinks it is the right front caliper. He thinks as it heats up a bit it is sticking. The problem is under visual inspection all the brake components look fine. He said all parts replaced that appear normal have to be sent to Ford and if they are found not to be defective the dealer is back charged. So, what this means to me is I have to take one more test drive in a few days, he will record the problem and then Ford will approve the replacement of the caliper. Pain in the azz, but whatever it takes.
Another update: Took another test drive and the engineer has narrowed it down to the rear right caliper. After it heats up it hangs and does not grab equally with the left causing the pulling. Monday morning parts should be in and lets cross our fingeres.
Update: I got the truck back and it appears the truck is fixed! Cross your fingers. I need more time on the freeway, as the traffic was bad. Here is a list of what they did.
A T103 VEH PULLS TO THE LEFT WHN BRAKING AT FREEWAY SPEEDS.
CAUSE: 6245 TEST DROVE, REMOVED WHEELS & INSPECT BRAKE SYSTEM. FOUND
RIGHT REAR CALIPER HANG-UP, REMOVED RIGHT REAR CALIPER & REPLACED. BLEED BRAKES.
REPLACE CALIPER ASSEMBLY. PART # 7L1Z*2552*A
I will post another update Monday morning or sooner as I have to drive 300 miles on the fwy this weekend.
I had the same brake pulling issues for the first 5,000 miles, but at about 5,500 miles it stopped pulling and they also seem to work much better (stronger) . I now have just over 7k miles so no pulling in the last 1,500 miles
