Let us know what you find.
Oleyeller, the calipers, rotors, and pads are all off a Gen II CTS-V (2009-2012). The reason the gap is possible is that it is getting close to maintenance time. I plan on changing the rotors and pads soon. As for the master, I am not sure. Never thought to look at that, but at the same time, not sure how that is accomplished. Any suggestions on how to verify the master is venting properly?
