Posted August 7, 200816 yr comment_255679 Hey guys, the other day I jumped in my 78 280z for a quick spin and I noticed the brake light was on. My brakes are fine and the emergency brake switch seems ok. After 15 mins of driving I heard a buzzing sound coming from under the passengers seat. There appears to be a relay there (brake warning?) I disconnected it and of course the sound went away. What would cause this and is there any remedy or does it need to be replaced?

August 8, 200816 yr comment_255686 I'll have to let a 280Z expert give a proper answer but I'd first check the master cylinder fluid level. I know that on a 240Z the brake warning light can come on if there's an imbalance between the front and rear brake system but on the 280Z there may even be a fluid level sensor are some other way of triggering the light.
