I did the brakes for the 1st time on my Super Duty. When I did the passenger side yesterday I noticed an extra clip on the outer pad. I put it on but do not know its purpose. First I thought it was a squeal tab but that is not it. It seems to put upward pressure on the outer pad. But why only the outside pad?
I did not install it on the drivers side but can do so if it is needed. I also do not see any reference to it in the ford repair manual.
I am not talking about the 4 clips that pull the pads away from the rotors, those are on.
You can see the clip I am talking about in the below video at the 9:20 mark. It is the clip already on the pad being held in place by his finger.
That clip was a later update to lessen brake noise that was identified coming from the outer pad. It should be installed as it was on your vehicle, to the leading end of the pad, not the end that takes the brake torque when decelerating. The Ford manual was written well before this clip was created as part of the normal vehicle maturing process.
The guy in the video did a couple of wrong things and that vehicle owner will be at some time buying a new brake hose, caliper, pads and rotor.

The leading edge, I read that as the bottom or lower tab of the pad as it sits in the caliper bracket. Is that correct?
Yes. Sorry, terms we use in the industry don't always translate easily into public life. The leading edge the first pad contact of a point on the rotor as its rotating in a normal driving direction, in this case bottom. The trailing edge is the top in this case, the exit point of rotor contact. The purpose of this clip is to keep the pad in tight contact with the bracket.

I have rotors and pads coming today for the front. The video looked straigh forward enough if not a little clumsy and heavy handed but I didn't see anything that might jeopardize the life cycle of the components. What did you see that was wrong so I can avoid them?

I'm willing to bet it was because he dropped the caliper and the hose caught it, possibly causing internal damage to the hose, which, in turn, can cause the caliper to not allow the brake pads to release.
Just my guess before Jack gets back to answer the question.

You da man!
Thanks so much for the explanation. I will feel much better about the pad install now. Reps inbound.

Almost anytime a hose plays the role of a hangmans rope its doomed to failure, and that "almost" becomes a certainty with calipers as heavy as on these trucks. Even with calipers of this weight the use of the bungee cord he used still puts a heavy strain on the hose, especially with some years on them. We used to take a foot long piece of brake tubing and make into an S or C shape hook to hold a caliper as soon as it was unbolted from its mount. The use of a clothes hanger is not sufficient.

Can you PLEASE post a photo of how they should go on?

I like to use something with less give. Stainless Steel 0.040 safety wire and hang it from that.
Things tend to stay put with that and a good twist.
I just finished up installing the clip in question. I can take a pic through my wheel a little later today. If that does not come out good I can take the wheel off again, no big deal.

I looked at some files I had when setting up training so we would all do the same rebuilding of the brakes and the pictures I have were before that clip was used.
The brake tubing worked fine for a few decades of 5 or 6 brake rebuilds per week so I think it's substantial (as long as the bend aren't linked). Someone could also use some 3/16 to 1/4" rod as well. They are commercially available too, but if you mass quantities of tubing laying around......
