Hi Guys,
Over in the M2 forum we've been having a debate on the pro's and con's of CCB's. I mentioned that besides the visible CCB wear indicators you also must disassemble and weigh the ceramic rotors - for wear. Its not necessary to do that now - although there is a min ccb weight loss of 100 gram per rotor. Here are some interesting pdf's on checking for wear on CCB brakes. Its nice to have friend's at BMW AG.
