Front brake discs... I need answer

[Marcus]

I cleaned and painted my front brakes and I'm now putting those together again.

Well I didn't mark which one of my discs are left and right.. So does it matter after all?

They are both in good condition. Other one got mark "K1" and other one "K3" on them inner side... Can this help?

Thanks!!

I don't think it makes any difference what so ever.

Are they curved vane? If not it doesn't matter
