Hey Scotti
I have not one but two Kia Sorento's. A 2019 and a 2021. The 2019 has 60k on it and needs brakes. I live on Long Island so i get the best of the elements salt air year round and damp snowy winters. I hate when I put on a shinny new set of rotors only have them turn rusty within days. Are there such a thing as stainless steel rotors or at least corrosion resistant.
No.
Stop looking at your rotors.
The brown sort of stand out against the black alloy wheels even from a distance.
Don't be too concerned about appearance. You drive a Kia, not a Rolls Royce.
That's pretty good. Where can I get a set of those.
I thought that rust forms on rotors naturally and is worn off after a few applications of the brakes.
he doesn't like the way it looks
You end up with two rusty stripes with a polished stripe in between.
I guess the message is:
1. Get OEM rotors.
2. Live with the Long Island rust or move.
3. Don't buy a Kia in the first place.
How often do you drive that car?
The 2019 has 60k on it and needs brakes.
I do a lot of traveling through out the northeast for work. I rack up mileage quickly.
It seems you don't use brakes often.
I didn't know this, apparently stainless steel rotors do exist for some applications:

Carbon-ceramic rotors would provide you with the appearance you are looking for, however I don't think you could find any made for your vehicle.
They are very expensive and typically used on exotic vehicles.
Only $1,500!
Stainless steel is not a good choice for brake rotors or drums.
It is soft and wears fast because most stainless alloys can’t be hardened. In applications like screws and nuts it’s also known for seizing.
They are absolutely terrible at sinking heat and their low carbon content translates to poor lubricity at working temperature. They warp easier.
Also they will still turn brown as pad material is deposited onto them.
I was thinking more like the ones that are advertised as being corrosion resistant or coated. They are more reasonably priced.
A coating? What do you think will happen to it when you use the brakes?
Coatings are great for making the discs looks shiny on the shelf or out of the box.
Thanks, I was surprised they existed for any application.
What about the sprays advertised for corrosion protection for rotors ?
Anything that's sprayed on the wear portion of the rotor would be scrubbed off by the pads. The pressure and heat is just too great. Not to mention you don't want to use something that would not allow the pads to 'grab' the steel and stop your vehicle.
There are some sprays that classic/antique car owners do use for long term storage, however I don't think that's what you are looking for.
I don't think you understand how brakes work, Mr Bob
I think I understand now. See Ya
"if the rotors are warped, the brake pads are warped too" ? Huh?
I think that's some warped logic.
@mmj LOL. Maybe Scotty wants to save on the time & labour of replacing just the pads, in future?
