One problem related to brakes failed has been reported for the 2006 Ford F-250. The most recently reported issues are listed below.
Driving down the highway and hit a bump in the road the truck started to do the death wobble and shaking uncontrollably. I have to slow down and jerk the wheel to get it to stop. Its increasingly getting worse and now doing it at lower speeds around 25- 30mph. This has almost caused wrecks with vehicles rear ending me, or wobbling in their direction. It also happened in a neighborhood with children playing, I thought I was going to hit the kids! the brakes also fail while beaking and hitting a bump. The tires are at the recommended pressure and that is not the problem. This is a very common problem as I have seen while doing more research. Im afraid this will eventually cause the truck to roll or wreck. Dont let the loss of life open this investigation again.
