Well I had this only happen a few times it seems to happen only when I get on the gas hard for a split second and then some jerk pulls out in front of me or pulls into my lane and I have to go from hard aceleration to hard braking in a split second. At first the brakes feel like there is nothing there then all of a sudden the catch. I damn near wrecked tonight because of some jerk decided to turn left same time I was going into the lane he was in front of me driving slow so I got into the center left lane early to get up to the light so I punched it to get a quick thrill then dimwitt decides hes going to turn left so I had to go from acelerating to braking like that. I put the brake pedal to the floor and and the truck kept on with the rapid aceration for a second or two before the brakes kicked in just intime to prevent me from wrecking into the dude he got a blast of my horn and the number one salute for his very stupid move. all I want to know is there a problem with my brakes and if anyone else had this happen on there truck.

 

I am not sure if this is what happenned to you but I have hit the brakes on my 04 F150 and due to the fact my feet are a size 13 I ended up hitting the accelerator at the same time as the brakes. just a thought.

 

The computer controlled throtle valve doesn't back off fast enough.

 

That is probable what happened to me going from smashing the gas to brakes in a split second the computer had some lag in it causing my problem.

 

I would suspect that it's not so much a throttle issue as a vacuum issue. There is a check valve in the vacuum booster that is supposed to maintain vacuum on the brake system. (That's why you can shut the truck off and get one good whoosh from the brake pedal) I would start there and see if the check valve may be bad. When you go to WOT, there is very little vacuum in the system, but the check valve is supposed to hold the vacuum just for that reason.

Either way, if it's an 05 with a factory or extended warranty, everything should be covered except the pads.

 

hmustang – Did you notice if the ABS light came on or not?

I just received this letter in the mail a couple days ago and it might be a good idea to look into with your dealer as well.

No my ABS light did not come on durring the situation.

 

I looked at the recalls section here and Ford needed to work on the computer concerning an ABS issue.I took my 06 in for an oil change and they reflashed the system stating there was an update.The update concearned the computer and the ABS system.

 

that is the reason to take it in,the letter is saying that if there is a problem the ABS light will not come on.You could be driving with problems and not know it.
