hmmm they were the nice AC Delco ceramics and the coated rotors from AC Delco. but i like the idea about checking the backing plate. i used the right lubricants and greases and the pins are nice and move freely, but i think next set i buy i will take a micrometer to the pads just to see how they are when new. sicne i will be buying micrometers, i will use them on my rotor too. if i have a lot of meat left for rotor, i will have them resurfaced instead of new ones.I've seen something get stuck between the pads and rotors which chewed them up but usually a groove effect. Guesses, bad pad or materials keep in mind both sides may be made at the same time just come in the same box, piston, brake hose, rough caliber casting, wrong grease on slides, etc. The metal backing on the pads can have burrs or not fully flat, trial fit and file or grind where needed before installing.
I've seen more nonconforming parts in a day in QC then most people will see if a lifetime so I don't trust any part until I check it on finish and fitment. Doesn't make a difference who's name is on the box as anyone can have a bad day at work.
