removing caliper bolts on B6 3.0 rear

[nudavinci64]

Has anyone had trouble trying to remove the 8mm hex bolts that connect the calipers to the axle.

I could not get them to move for the life of me. I am guessing I will need a breaker bar with a 8mm hex socket suggestions?

Also Bentley says to always replace those bolts has anyone used the bolts again?

i will be replacing rotors on the rear and installing s4 fronts so need to know if i need to go out and buy the calipers bolts for front and rear again.

I do not remember replacing them when I did the front last time.

yes they are a bitch, you need a stubby allen socket or i used my regular allen socket and a small wrench to turn it (had to double it up) do you understand?

yeah i see what you are saying.. I was using the wrench but did not double up.. I was thinking about buying a 10mm hex socket and using a breaking bar wrench to loosen. I think thats what I had to do for the ones on the front.

Did you replace the bolts afterwords? Bentley says to but i don't remember doing that for the front
