I'm looking at the rotors on my F430 with 20k miles and note a lot of scoring. Is this normal? The pads are at about 50%. The pre-purchase car inspection mechanic did not raise it as an issue. Image Unavailable, Please Login
Forgot to add that this is a 2008 so I assume I am looking at carbon fiber. Very expensive to replace.
Hard to tell from pic .. but I do not see flaking or pits from pics .. are they fairly smooth ? Sent from my Moto G (4) using Tapatalk
I compared to other cars with similar mileage and the 430's are rough. Others are smooth. But they are steel not carbon ceramic. Thinking it has to do with the carbon. Might need to know the typical life of carbon ceramic rotors. Sent from my Z1 PRO using FerrariChat.com mobile app
With normal driving ..life time of car .. track ..maybe 10 days at track Sent from my Moto G (4) using Tapatalk
I still see the original machine marks on the carbon ceramic surfaces. A) they are just fine B) they will continue to last a long time. I was getting 25-30 track days on my F355 brakes with one trip to the lathe about 1/2 way through. I only got 5 track days on a set of pads, though.
Thanks. Not sure if the car was ever tracked but I don’t plan to. So with 50% of pads driving maybe 3-4K a year I’m good for a while. Sent from my iPad using FerrariChat.com mobile app
Those rotors look fine for CCM brakes. If they were tracked or used very hard, they will develop holes or pits in the surface (which yours do not have). The percentage of life remaining of the rotors is calculated by the instrument cluster and should be looked at during a normal maintenance service using a Ferrari specific diagnostic computer. They typically do not show wear on the friction surface, but lose mass over time. Rotor replacement is determined by looking at the calculated wear in stored in the instrument cluster memory and weighing the rotor to see if it is below the replacement weight.
