Measure the thickness of the wear material, that's fastened to the metal backing plate.It was at the local Ford dealership. I don't distrust them, yet.
I'm not opposed to checking it myself but I'll have to read up on it. What tool do you use to check the thickness?
A ruler would work.

Its just seems fishy is all, that's way to early for them to be worn out.
But you don't say if its a brand new Expy with 14K miles or ???
