searching the archives. the A4 tech article shows removing the plastic caps to access the 7mm bolts to remove the caliper. something tells me that's not right for the A6/ar. (now that I look again, the bolts under the plastic caps don't have a hex, int or ext, on them) However, i can't get those 21mm bolts to budge. I only want to get the rotors off, not replace the caliper. help, please.

messy job, by the way, geez

You have to take the caliper off to get to the rotors. Paracaidista has the size right on that.

I did the job by only unbolting the top 21mm bolt and loosening the bottom one to swing the calliper

thx folks. no luck gettin' those beasts loosened. may try again tomorrow.

trying to do it from under the car will probably not fly... The bolts are fine thread and they ahve some anti-loosening pattern on the contact face of the head. You will need a decent size breaker bar.

Breaker bar is the key. I use an old tie rod from my F150 for the task :-)
