    How do you assess ceramic brake health?

    Rotors: I believe the rotor material to be the same chopped brembo carbon material like Porsche's pccb, where rotor status is based on oxidation level through the core of the ceramic. It seems wth the Porsche, they used to remove and weigh them, but now it think they use some type of scanner to determine the oxidation level.... What's the proper way for Ferrari?

    Pads: I found a post by Aldous

    https://aldousvoice.com/2018/06/14/ferrari-ccm-brake-pads/

    and he says scud pads are 10mm thick new, wear marker warning sensors are at 4.7mm, yet a pad he measured at 5.7mm was showing the brass studs which damaged the rotor. What's the recommended minimum thickness to change pads?

    Thanks,
    David

    You are correct for the 360/F430 non silicone top layer type rotors: it is oxidisation. Visual inspection has always served me well. Weighing is inaccurate because material transfer in-extremis can skew the reading.

    The brass studs do not damage the rotor.

    How do they visually change when they oxidize?

    There are some good reference .pdf’s from a post on the BMW forum: https://f80.bimmerpost.com/forums/showthread.php?t=1115439

    You can see the oxidation as spalling of material, like pitting. Weighing them will also work, but you have to clean them first. The min weight based on weight at time of manufacture is engraved on the rotor. Basically as the carbon gets too hot it burns, or oxidizes and you lose material.
