Like so many automotive items, brake pad material selection is a topic of debate. In fact, it has been debated on this forum at least once.
Some of us use ceramic pads all the time (as I do) and have excellent results (great braking performance, low noise, low/no dust, long life of both pads & rotors), others not so much.
Here is a link to a discussion we had and you’ll see opinions on both sides.
I’d still go with the ceramics to be on the safe side. I’ve had good results with Wagner Thermo Quiet Ceramic pads. Don’t just take my word for it. As you can see @asemaster indicates that those are the pads (ceramic) specified for your vehicle. I would trust his judgment.
Oh, and that ASE in asemaster?
ASE = Automotive Service Excellence, a leading organization of mechanic training and testing that leads to certification as an ASE technician, widely esteemed and recognized in the car repair industry.
Basically, a master is certified in all areas of expertise, Engine Repair, Automatic Transmission, Manual Drive Train & Axles, Suspension & Steering, Brakes, Electrical Systems, Heating & Air Conditioning, and Engine Performance.
Metal to metal means the pad material was worn through or missing from the metal backing plate that It was attached to and the metal plate was in direct contact with the metal brake rotor. It was grinding and metal flakes were being expelled, settling everywhere and rusting.
Try and find a good wheel cleaner liquid to remove it. I have used DUB (developed by Meguiars) to clean brake dust and brake rust from rims. Follow the directions on the bottle.
