followup Question - What is the minimum rotor thickness one should expect to see stamped on the rotor. No such stamp is visible. Question - Where can an illustrated parts catalog for the 308 brake calipers be found? Thx.
Can't recall if it's stamped on the rotors or not, but the 308GT4 WSM states: front = 22 mm nominal, 20 mm minimum rear = 20 mm nominal, 18 mm minimum http://www.eurospares.co.uk/partTable.asp?M=1&Mo=592&A=1&B=32815&S=
