nissan terrano II brake warning light lit up

[dawni007]

HI
The brake warning light has just lit up on my dash. The brakes were done not that very long ago and there has been no noise or squealing. Is there another reason why this light would be on does anyone know??? I heard that if moisture has got in to the blake fluid then the light will come on??? Any ideas gratefully received.

On my Terrano it was the servo. Replaced the master cylinder and servo together as splitting them and matching them was a nightmare, also check that the switch on the brake fluid cap isn't faulty, change cap and switch together. Not saying this is whats wrong with yours but it is what triggered the warning light on ours.
