brake fluid leak between reservoir/MC

[Murari Srinivasan <murari@cfar.umd.edu>]

Hi Quattroheads,

here's another tickler (perhaps a no brainer
for some). I seem to have a brake fluid leak
at the point where the brake fluid reservoir 
connects to the MC, in my 5ks. 

Could this be the plug between the two that's
given way ? The MC seems to be ok, although
I haven't performed the dreaded 1,2,...20 (40?)
push test recently.

Would I be able to order this plug alone 
separately ? It doesn't look as though 
the MC and the reservoir are sold together,
so I was under the impression I could just buy
the plug, and achieve a cheap, correct fix
(Does such a thing exist at all ? :)

many thanks,

Murari
