I have a 2008 Expedition Limited which I bought for my wife. It has 27,000 miles and we baby it.

My wife was slowing down to turn into the driveway. She heard a screeching sound, the brake pedal went to the floor, swirving around, and the car would not stop. The ABS / traction control light came on the dash too. She rolled on pass the driveway because she couldn't stop the car!

I found a few articles on the web describing the same thing. They said their cars had been to the shop several times and the dealerships could find no problems, no codes, evidence etc. And of course, my dealership is saying the same thing. They have consulted the online help and ran multiple tests today with no luck. Everything works out fine.

I am scared to death my wife and kids will get hurt, but we have to have the car everyday. I found on the web that it may be the hydraulic cylinder.

Any ideas? Thank you.
