[Biturbos4] Rear caliper pistons on B5

[Grant]

Ahhh, I see you also don't have the shop manual. :-)

Every Audi made since about 1980 has required a giant hex key to 
"screw" the rear calipers back in.
I suggest you buy or borrow one.

I also dont have the bentley for the '00-03 S4, but I could dig up my 
old '84 or '91 manuals if you need me to peruse them for you.  Let me 
know.

Not sure if any damage can come of the brute force method.  Never had 
the heart to do it.  When I faced the same problem back on my 1984 
4000q, I put the old ones back in until I got the right tool.
