I purchased the pickup just after it was inspected (Virginia). I did my own inspection later, and found many problems including the parking brake shoe linings completely missing, and a 4" gash in the top of the gas tank.
Then I noticed the rear brake pads were installed with the notched end facing down.
I believe this is incorrect, but don't know if it is serious.
There are many YouTube videos for the pad replacement. About 50% show the notched end at the top of the caliper; two mentioned this orientation. The subject was completely dismissed in all other videos I checked.

I installed new rotors, calipers, and pads with the pad notch at the top. Am I correct, or is it just a matter of choice?

The original intent of the notch was to make it easier to assemble the brakes on the assembly line. The notches go to the bottom so that during assembly the caliper is set in place with the notches and gravity holding it in place. It simply rotates into position and then the pins are put in. Service info shows that orientation as well. As for it being serious, not really. The next generation of F150 doesn't have the notched end, however the Navigator/Expedition uses pads with notches at both ends.
