So I just changed out my semi-metallic pads to ceramics today (good bye brake dust) but my old drivers pads were almost to the metal and my passenger side pads had about 50% left. What could be causing this?

Sticky caliper slide, sticky caliper piston, bad fluid, air in the system....

Big D,
Todd is 100% correct. Sticky caliper slides, sticking piston, or bad fluid or air in the fluid, are the usual suspects.
Ford does not appear to lube the caliper slides when they install them at the factory, so that would be the first suspect.
The sticking caliper piston can be detected if you open the bleed screw before pushing the piston back, and you push it back using your fingers and not a C-clamp or such item. You can actually feel if the piston is binding, or if there is corrosion in the caliper bore.
It is also not wise to push the old dirty fluid back into the ABS system since that crud in the ABS system can lead to expensive repairs. You also need to flush the brake fluid every 2-3 years anyway, so why not do it when you are doing a brake job??
