Carrier-to-Housing Bolt on Rear Calipers - Size and Type?
My rear calipers arrived today (for my 99' A8 pre-facelift) and, to my surprise they came complete with the caliper carrier brackets. So, I only need to undo the two large carrier-to-housing bolts in order to attach them. These bolts appear to be allen-key bolts. Does anyone happen to know the size, so I can go purchase the correct one? I fear that such a large size would not come in your run-of-the-mill set. Many Thanks - Michael

Even with the tire off they are hard to see well Paul.
That is why I was hoping someone might come to my rescue with the information. But if need be I can operate a mirror and a flashlight simultaneously, I think. If they are "triple square bolts" I have no idea where to source the tool. (If I don't get any further replies I will have to get more investigative in the morning.) Thanks.

pretty sure they are 8mm allen/hex. I took these off my old car last week and still have the bolts.
I have the "Lisle" set with about 8 sockets which you can find anywhere. I can dig up the bolts if you want.

You are right - 8mm allen/hex.
Did one today, will do the other tomorrow. Incidentally, if you want to actually use an allen key, you will need a ball end, preferably with a handle. Otherwise, I recommend a 8mm allen bit.
