What specifically does the red BRAKE warning light mean in a 2002 VW Cabrio?

Question

I don't have a manual for my 2002 VW Cabrio. The brake warning light just came on - The word BRAKE in red capital letters. Is this a brake fluid problem, a sensor problem, etc.? The parking brake isn't on, and it drives and brakes fine. Just had my brake pads changed in March of '08, so that shouldn't be the problem.

Answer 1

Could be 2 problems, parking brake engaged or low fluid in the master cylinder.  

Answer 2

it could be any of the above, low fluid level,a pressure difference in the two halves of the system, a brake lamp that is out, an e brake that is still partially on, or pads that have worn to a minimum. my best advice is that you  get the brakes checked out by a professional.  

Answer 3

Brake warning lights come on when you are low on fluid.  Also, in some vehicle them come on for a few seconds when the vehicle is started.  It could also be a sensor problem.  I would take it to a shop, and they will be able to plug into the computer and read what the computer says is wrong.
