It may be normal for the rotors that they installed, but definitely not normal for the OEM rotors which are E-coated. Rotors with this feature will have a bright, matte silver finish. There are lots of aftermarket options that are cheaper than the OEM counterparts that work fine. Just look for any fully coated (fully coated as in not just the hat and edge) rotor and you should be fine. FWIW I have Raybestos rotors with their "Element3" coating with Powerstop Z23 pads installed up front and they're great. It takes massive amounts of braking before I notice any fade.I’m very disappointed with my new Mopar Front Brake Rotors that my dealer installed to replace the original brake rotors that were on my van since new. Within a week, the hub portion and edges of the ventilation fins had developed a bright orange layer of rust. The service manager says it is “normal” and there is nothing they can do. My original rotors never did this and that is why I had the dealer do the work, so I would get factory parts. Now I find that all rotors are not the same. Some have anti corrosion coatings which would prevent this unsightly issue.
im considering replacing the brake rotors myself with a better brand. Soooo disappointed! Any suggestions on a better aftermarket replacement rotor? View attachment 50865
