[s-cars] Brake light staying on after start up

[Premiere Investment Properties, LLC.]

Hi all
I just bought a 92 S4 last week and am trying to work out the bugs on the 
car...The brake light(the little red one, when you pull the e-brake) will 
stay on for 10 second or so before it will shut off. What could be the cause 
of this. Its been awhile since I've owned an audi and still a little rusty
Thanks for any help
Tim
