    Coated / plated rotors vs bare rotors

    I am doing the front brakes on my 2014 Mirage very soon. When I go on Rock Auto, they show that there are Coated (I assume they are zinc plated) rotors for improved rust protection. Do any of you have experience with these type of rotors? I would love to hear how well they work.

    I put Raybestos rotors on when I replaced the pads last time. They offered two grades of rotors, and I chose the higher grade. My logic at the time was that even the higher grade was significantly cheaper than OEM. Mine appear to be coated, and have not rusted. However, the stock ones I took off hadn't rusted, either! Rust isn't a huge problem around here.

    The stock ones mic'd out okay, but one side had a slight warp/pulse. I will have to check my records, but I think I did them at about 90k?

    Myself, I just buy the cheapo uncoated rotors and decent pads. There are some places where I don't see the point of paying extra for something. Coated rotors are one of those things. Premium gas and unobtaium spark plugs are some others.

    I have zinc-plated rotors on my wife's daily-driver Eclipse. They did well for a couple of years but they eventually rusted like normal rotors. If I ever get those rotors again, I'm still going to go ahead and paint them for extra protection. If they only cost a few dollars more, I would definitely get zinc-plated rotors.

    I painted my OEM rotors and calipers when my car was new. Here's what they looked like after 50,000 miles of daily driving...

    I know they look a little rusty, but some of that brown color is brake dust. If they start rusting, I will toss them in a bucket of Evapo-Rust overnight and paint them the next day. I'm a bit OCD about that kind of thing because you can see my rotors and calipers through my wheels...so I have to keep them somewhat presentable.

    Be sure to price brake components here, too: https://brakeperformance.com/

    The surfaces don't look that bad for that kind of mileage. If you tossed them in some Evapo-Rust overnight, all the rust on them would disappear. Then again, the entire rotor may disappear.

    Do you guys even bother resurfacing them? I haven't cut a rotor in years. They are just too cheap to buy new.

    I've got an pretty old lathe that I don't know the history on. I'm convinced the arbor is off center. The few time's I've used it weren't very successful.

    No matter which rotors you get, Daox, I will make one suggestion given your locale. Put a little grease or anti-seize compound around your hub after you take the old rotor off. Or, after you fight the old rotor off!

    Here is why I ended up going with the coated rotors... I'm not sure if these are original rotors or not, but they're not in that great of shape.

    How many whacks from a bfh did that take to get off? Looks pretty dry around the hub. There's always time for lube.
