C6 GS & Z06 front calipers - check your pad locating pins!
At Road America with NASA this weekend, coming into turn 5 under heavy braking (about to turn) and I hear what sounds and feels like I went over the rumble strip on the right.
After the session, I'm checking everything out and find this. Apparently the locating pin backed out, the rim spokes hit it, and ripped it out of the caliper (the rim is damaged as well). VERY thankful this didn't cause a serious accident.
So, if checking these pins isn't on your list... you may want to add it.
I was considering a brake upgrade this winter, now maybe that is moved up to this fall, and will be checking the forum for a used rim.

Stay safe, stay vigilant with your maintenance!
This is the second post I have seen regarding this issue.
Any ideas (beside BBK's) for a cure to this ?
How often, if any, have you taken the pins out of the caliper? Mine seem to be seized in the caliper after almost 9 years and never having been out. I always remove the caliper to change pads. Tried to get a pin out of one the the calipers last year and broke 2 torx bits before I gave up. Glad you dodged that bullet.

I have a 2012 model year car. Tried taking them out 1 year ago (after 3 track weekends), and all but 1 were seized - and I made sure to torque it down when re-installing. Since, I've always removed the calipers as I use one-piece pads.

I purchased pins with 10 mm hex heads that have a few less threads than the stock pins, haven't had any issues yet. Switch back to stock pins for street. I have heard of guys that have been able to free seized pins right after a track session when brakes are still hot.
