Brake Issue

Replace the booster. Fluid flushes are good but never change anything dramatically.

Mechanic said booster was good. Its going in for an oil change on friday I used the opportunity to set up an apt for them to look at the brake system too.

Update: Not sure why I thought this would be any different, but dealer techs and service manager say that they don't notice anything wrong. Meanwhile, none of them were able to trigger the ABS with panic braking, unless they wet the pavement. So no idea what's wrong, and everyone thinks I'm nuts.... again. Rather frustrating.

Getting a recurring, yet intermittent C109F code on the truck. Pointing to a bad vaccuum signal or sensor, i believe. Any insights?

Thanks,

Final update:

Turned out that the batch of brake rotors and pads i got from R1 concepts (drilled and slotted rotors, super duty pads) were faulty for whatever reason. Swapped for the Motorcraft pads and rotors at dealer, and now the truck stops. The weird thing is that the swap cleared up the increased sponginess and the inconsistent pedal feel. I can't explain it.

Truck stops now, though. which is nice.

I can, that's aftermarket hoopla to make money, I will never run slots etc.

I see all this as a way to get $80 for a $12 Chinese rotor.

Chinesium alloy.

In any event, it works now.

Thanks for getting back to us one this one. One more reason I don't buy China parts. Simply not worth the grief.

My 2008 brake pedal felt spongy like air in the line, my opinion, and I took it in while still under warranty. Explained pedal slammed close to bottoming out in panic stop. I could double pump pedal to get firm pedal and brakes worked "normal".

We had Ford "specialist" come to check it and he said it is OK. Service Manager let me drive other new expeditions and they felt the same. Even drove his pickup and it felt that way.

Now, less than 60,000 miles, brakes still work the same but I work different.
