Heres the deal...
Hello, 05 F350 6oh 48,000
Okay, maybe this is normal, but it doesnt hurt to ask right? While at a light and the truck is at idel, if i let of the brake just enough to let it idel foward, is it normal to feel a surge in the truck? i does this 4 times a second, and it just seems like its chugging foward. Seems to be getting worse in time now.
Anybody else feel this? maybe im just making something small into something larger, but just want to understand whats going on here.
Thank You for your time.
Sean

Mine does it as well. I wouldn't necessarially call it a surge per se, but I've attributed it to the brakes inability to hold the vehicle in place without adequate brake pressure. In my case, it really only seems noticable when I'm facing downhill and I don't have the pedal firmly planted. The truck won't exhibit this issue if it's on level ground or on an incline. So I've attributed it to the weight of the truck coupled with the power of the truck that's trying to propel it forward.
btw... same year truck with 30k.

Guess I never thought to much about the brakes being warped. I guess I thought when the rotors get warped, you'd start to feel pulsations in the pedal as you decelerate. I don't feel that during regular stopping, so like I said, I never thought that I might have a warping issue.

I have noticed a little surge when the AC compressor kicks in when using the AC or defrost. That is normal. Just a thought.

I know what you are talking about. I believe it is attributed to the brakes running off the power steering pump, instead of a vaccum pump like gasoline vehicles. For some reason, you have to apply a little more pressure than usual. I typically notice it when sitting in a drive-thru lane at fast food places, especially if I have bumped it up into neutral.
