Hello fellow BHPians!
So I recently bought a new GT Line 1.0 in July in Mumbai. I recently noticed my brake discs are quite rusted. The car has been driven about 120 0km in the last month . Since it was a Jan 25 manufactured model, it would’ve been lying in the yard for a while.
I informed my service advisor about this because he didn’t point it out during the first service which was a week back. Now he’s saying that I can come next Monday and get it “skimmed”. No idea what that means.
Is this a cause for worry? Or will the skimming make it alright. Or should I ask for warranty replacement of the brake discs since the car is brand new and there’s no other reason for the brake discs to randomly rust so soon.

I think this is normal as long as it doesn’t affect the braking .
Here’s what BHPian NomadSK replied:
Nothing to worry, that’s a superficial rusting, natural oxidation phenomenon, with a passive layer of iron oxide formation because of exposure to moisture and oxygen. Just run your car regularly, such layers won’t be formed and you won’t be bothered !!
Skimming is actually required when either your discs are warped or have enough scratching to reduce the contact area with the pads, generally happens after a long long time. So just avoid it at any cost on a relatively new car, else you are just reducing the life/thickness of your discs.
I don’t think so anyone would do a warranty replacement.

This is perfectly normal. Don’t lose sleep over it and definitely don’t get it skimmed.

Spirited driving and some heavy braking will sort it out, Just find a safe space to do it.
