[s-cars] How do I remove the brake booster?

[J. Khang]

Hi, guys.

The S6's brake pedal is leaking fluid and I have a new brake booster ready to go 
in. However, my mechanic can't work out an easy way to remove the leaking brake 
booster, it's buried behind a ton of stuff and foam insulation. Can someone who 
has done this before please tell me whether there is an easy way to do it or do 
we have to strip half the dashboard out to get to four nuts!

The car is a RHD S6 but I'll settle for a description of the LHD S4/S6.
