Over the last couple months when we go to apply the brakes the pedal will have an initial "kick back" but brakes fine afterwards.
The X has 30k on it and within warranty,no rotor warpage if that comes into question.
Any ya'll have had similar synptoms with your Excursion/Superduties?

Bill,
I wonder if your calipers need lubricating? They could be sticking a bit on a initial application of the brake pedal. I just installed new brake pads the weekend before last and my front calipers were completely dry...no grease at all. Here's a pic for reference...don't know if you've done this before or not. The caliper is 2 pieces. The ends (on the left side of this pic):
...have rubber boots on them that will slide off as you pull the caliper apart. The cylinders that the caliper slides on should be very well lubricated. Mine weren't...it's very easy to see once the rubber boots slide off.

I know what you are talking about but I do not know what it is. This weekend I was flushing the brakes/power steering, when I was test driving it, when I would stop I press the brakes down farther then it requires to stop when it hits a certain point it acts like a valve opens and then closes quickly. I am not sure if it the Hydro system that they have for the brakes and power steering. If you find out let me know. Mine only happens when it is pressed harder then is required to stop or just sitting in the drive with it running and press the brakes very hard.
Sound similiar?

The Superduty/Excursion calipers have rubber sleeves? If that's the case can they upgraded to stainless steel sleeves like we do on the 87-93 5.0L Mustangs as the calipers had a tendancy to stick on the stangs.

Eric is correct in looking for a dry caliper bolt(s). However, there's more to the story. I cracked the code on another board; your culprit may be sticking brake pad backing plate. If your pads are the steel back type (performance friction brand among others), the 'tabs' at each end may not slide smoothly through the 'slippers' that snap into the caliper.
I took a file and dremel tool to the tabs, squared them off, removing the lumpy paint in the process, then polished down any sharp edges with the Dremel grinding wheel. I used Brownell's Phospho-Blue gun blueing formula to treat the ends agains rust, then greased 'em up good before reassembling everything.
No more brake 'kickback'.
Let us know if this works for you.

Bill, I'm not familiar with this upgrade. The rubber sleeve/boot is very much like a rubber boot on a shock of your suspension. I'm not sure how a stainless steel sleeve could be added since the rubber functions simply to protect the bolt the caliper slides along when the brake pads are compressed against the rotor.
Hawkeyes, thanks for the tip on the tabs of the pads. I just installed new Ceramix pads but haven't noticed this problem. The tabs did seem to fit fine. Good info for the future should anyone else have the kickback problem!

Hawkeyes actually were still on the original factory brake pads.
I may check out the brakes this weekend weather permitting to see if anything is sticking backing plate wise

Eric actually the stainless steel caliper sleeves aid the caliper in compressing and releasing straight & free instead of the rubber sleeves which cause the brake pads to grab unevenlycausing premature wear of the pads and in some cases damaging the rotors.
I install them on each 5.0L Mustang we acquire,it helps braking performance alot so I'm unsure if the same could be done with the trucks.

Got it...that makes more sense now. I do recall the caliper does have a tendency to compress/decompress unevenly when I was relubricating them. I would imagine something similar is available?
Do you have any pics of them installed on the calipers of your Mustang?
