Why is it so hard to find good help?!
Took the truck to yet ANOTHER Ford dealer. The guy drove it, said "Rotors are warped". OK, that was actually a consideration. Then he punched some stuff into his computer, and said "With parts and labor, it'll be about $300".
GULP! For rotors and pads? (All this without so much as bending down to even LOOK at anything under there.)
"I'll get back to you", I said.
Finally, I took it to Brakes Plus for their free diagnosis. Guy drove it. Came back, said "Yep, I feel it", put it up on the rack, took the wheels off, did some measurements, and the rotors WERE warped.
He said, "Well, it's not dangerous, just probably annoying. You can wait, or we can do it now. $40 total to turn the rotors. You're pads are still like new, with really no wear apparent."
I asked him about doing it at higher speeds, and he said he suspects the high side of the warp could be doing some slight grabbing.
Gave the guy that worked on it a $5 tip for a sixpack, said "I'll get back to you".
Went back to the FIRST Ford dealer, who looked at it 3 times already. Gave them the diagnosis. "Well, according to the computer, you said "Intermittently, at any speed". If you had said specifically, "While braking", we would have suspected that".
"EXCUSE ME?! The guy, your EXPERT, drove it several times. He SHOULD have been able to feel it. The Brakes Plus guy did. It's not up to me to diagnose the truck. It's up to YOU to take my symptoms and narrow it down."
"OK. Well, we can do it under warranty. Saturday morning, 9 OK?"
"Yep." So, this will be my FIFTH Saturday morning in a row taken up with a supposedly simple problem.
Truthfully, now I really don't know if I even WANT the Ford dealer to do it, even under warranty for free. May be worth the $40 to have it done by Brakes Plus, who seemed to know what they were actually doing.
At least I know now it's not dangerous for the time being, and HOPEFULLY that will take care of the problem.
Dunno, though, how they got warped. I use the the engine and easy downshifts quite a lot, with minimal braking just to slow me down to speed. And at least 90% is highway miles. Although, I have had to do some fancy braking and steering maneuvers on the highway to try to avoid idiots.
We'll see if this works. Just thought I'd post this for anyone who may eventually have the same symptoms.
