I've got the same darn problem on my TEVES. Just weak brakes.

Slightly off topic, is there any special procedure to bleed our brakes, other than depressurizing it?

See http://reatta.net/brakes/brakes_flushing.html for the Teves - should be flushed every couple of years. Note the process for bleeding the back is different (key on) from the front (key off).

Padgett'* got the right link for ya

Since the Teves resevoir is pretty big, and the fluid circulates in there, before flushing/bleeding the lines I would remove the hose on the back of the resevoir and let the whole thing drain. Replace the hose, fill it back up properly, and drive for a day (please do verify the system'* working ok before you get on the road though).

Next day, drain again, refill, bleed the lines, and you'll have all nice and clean fluid

Keep in mind that a brake light, even intermittent, can be a warning of a failing master cylinder.

Don't just live with it. Make an attempt to fix it very soon. Please check your MC for signs of leaking.

I just read the topic again. Your quote above concerns me. You don't have an ebrake switch issue at all. It'* totally unrelated. You very likely have a master cylinder failing. I suggest not driving the car until it'* diagnosed and repaired. If the MC fails while driving, you are going to wreck. Especially this time of year.
