I know this should really be in the T/B/S forum, but i thought i might get a better response here.

My brake warning light has came on,

(!) , <-- that one

The manual says that it is most likely the fluid levels; but, could it be the pad/disk levels? given that i wrecked them at a trackday a week ago? (i haven't driven or started the car for a week)

Thanks
Crush!
