Just got off the phone with the owner of the local NAPA who's a friend of mine......and I buy most all of my parts from his store. He tried a set on his 1/2 ton Ford, with the same results, and not even when towing. He brought the subject up with their brake rep who said that the ceramics are offered for trucks, even trucks that were originally equiped with semi-metallics, because that's what people want, for low dusting reasons........and that initially their engineers didn't know the ceramics would fade/fail under hard, heavy load, towing type braking applications that trucks/suv's generate.
Anyway, he's taking my pads back and issuing a refund. Hopefully he'll also advise his counter people to use caution when selling these to truck/suv owners.
