I bought NAPA's Premium brake rotors and their Proformer disc pads. The rotors are coated everywhere that doesn't contact the brake pads. The cast iron used in the rotors appears to be a little different too - has a different sheen to it, where it's machined for the disc pads. I'll have a story about all this once the job is complete. I replaced the rear sets about 10 days ago because of metal on metal (caused by rust), but the front sets are scheduled...
