Rookie question on "'bomb' failure sensor"

[JMGarciaJr@aol.com]

For what it's worth, on my 1992 S4, the dashboard "Brake" light has been
acting funny. Whenever the handbrake is released, it takes a few seconds to
turn off, and it comes on briefly after hitting a bump or some other road
surface irregularity. Is this something to be seriously concerned about or
just something minor and annoying to be dealt with at the dealership (my car
has a 3/36 warranty) when I take it in 1st thing Monday?

Concerned but not in a panic,
