Brake Light Shenanigans

[Al Powell]

The brake warning light on my 1990 200 is becoming pesky.

The bomb is known good, passes all pump-down tests, and is relatively 
fresh.  No problems with Pentosin levels, although a past leak forced 
me to replace the front half of the HP hose last summer.  No leak 
now.

But the darn brake light takes 30+ seconds to go off in the AM, and 
when the car is warm, I sometimes get flickers from it while idling 
at a stoplight!  It's clearly a non-bomb related problem.

Any BTDT's?  I think I recall some discussion of a possibly related 
problem in the past couple of months, but I can't recall specifics. 
 Was there some mention of a check valve in the pump?

TIA, friends.  Direct replies are appreciated.
