Perhaps this has to do with your technique, which you have described
in a previous post as follows:

"Here is my BTDT. My local wrench taught me this. I replaced all the plugs
and O-ring using a large screwdriver. It was easy and I didn't have to buy
any special drag link tools either."

IMO, this suggests the caps were not tightened to the torque
specifications when you installed them (with your new o-rings). So my
suggestion is to spend a few dollars (kroner?) on a draglink socket,
and do the job right. Also, don't forget to _lubricate_ the new
o-rings (that's another cause of premature failure.)

Your Bentley manual? Audifans archives? Do a search on the term
"bomb" (in SJM's web site) and it will bring up dozens of references
to the "brake accumulator" (i.e., used for power assist). IMHO, it's
a bit dicey to be doing your own maintenance on this critical
hydraulic system before having an understanding of its basic
functions.
