[s-cars] Brake Light Problem Back Again

[matt ludwig]

Douglas,

it may sound very naive, but could it be dirt/debris in the system  
that has either worked it's way loose (lining of high-pressure hose)  
or just old, gummed-up residual fluid from some other time it leaked,  
that was still in some crevasse?

I have this "type" of symptom on my avant as well (when i was driving  
it) and i believe i need to flush the system several times to get it  
cleaned out. Yours may not be this at all though.
