United KingdomSame as the front discs all good easy install shame to see the coating disappear so quick but good feel during breaking in, that’s as far as I’ve got
Thanks for your feedback - obviously the coating is to protect the edges and bells on the discs from going rusty, generally speaking, you wouldn't be able to apply a coating to a disc face that stays black like this as it's where the pad and disc face wear together.
