break warning light coming on but why

hi there i have a a s reg 1.6 golf i am currently having a problem with the brake warning light coming on when the car goes past 2 thousand revs the brake fluid level is fine the brakes are all working correctly could this be a fault on the ecu any advice welcome .......

hello there! is the brake warning light red or orange?
do you have abs brakes on the car?
is the emergancy brake lever(peddle or handle)coming all the way off?
if that speed sensor is loose or damaged and your car has abs brakes it's posible the brake light problem will get solved when you get that fixed.

the brake warning light is red when it comes on

hey there if the hydralic brake system is free of leaks and the brake fluid stays up I would look at the emergancy brake switch make sure thats working and if no problem there I would check to see if you have a proportioning valve and make sure that switch is working properly . could there be air in the brake fluid somewhere yet? does the brake peddle feel spongy if not the problem is probably electrical, and with out looking at a wiring diagram iam at a loss to where the problem might be . thats the best I can help for now.
