[s-cars] Brake bleed tools

[Ron Kirkham]

Hello folks,

I need to replace brake fluid on both my '93 S4 and my '98 A8, and would
like to do the jobs myself.  I recall some rather strong opinions on one-man
brake bleeding tools, and would appreciate some suggestions on the tools
that some of you have used, and would recommend I invest in.    

I am also assuming that these tools will work on (gasp!) non-Audi vehicles?

TIA,

Ron
