spongey clutch
After taking my '99 f250 superduty in for recall work (on parking
brake cable) I noticed a dramatic difference in the integrity of
the clutch pedal. The pedal was much softer and spongy than before. Coincidence or not, it is not the same as when
I left it to be worked on. Since then, the dealership has replaced
master and slave cylinder, to no avail, and now is replacing some sort of switch? Basically, they are clueless. Only clear response
I have gotten out of them is that some trucks have this "sponginess"
in the clutch, and some don't. My truck has 49,000 miles on it.
My concerns are: Why can't they discern the problem?
Did they cause it?
Is there some kind of defect?
Most important..what do I do when the finally
say, there is nothing more they will do for me?
I have heard some concerns about hydraulics being too close to
the exhaust, and this causes problems.
Have others had this problem? Is it a defect of something I will have to pay to have fixed?

You have air in the system.
The hydralic setups in newer Ford trucks aren't engineered very well at all when it comes to bleeding.
I'm not 100% sure how they are setup on the SD as far as bleeders go,but I can tell you what I did on a couple of Ford half tons and maybe this can be applied to the SD .
On the half tons,even after bleeding,there is still air trapped in the system.Here's what you do.Push the clutch all the way in and then let the pedal up swiftly.After about 10 or 15 cycles the air was pretty much all gone.Don't push down real fast because there will be an extreme pressure rise and could damage hydralic components.Like I said release the pedal swiftly several times and see if that works.
