I will be doing some wiring cleanup in my engine bay and wondered how critical this is. It basically tells you when your brake fluid level is low, right? If so, I only trust most stock indicators as far as I can ejaculate them. If I check my fluid with regularity, would I really need it?
OK, sounds good. I do have to keep a few things on that particular harness, so it wouldn't kill me to keep this one too. Plus, it's really close to the firewall, and should be easy to re-route if I decide to make any wiring changes.
He means the light is dual use. It tells you when the brake fluid is low, and also comes on (in conjunction with the battery light I think) when the voltage is low.
Honestly, I don't know if this is by design or a side effect of the mechanism by which the brake fluid sensor works.

It is by design. And eat your words Andris! John Lindsey in his #46 SE-R came in after the two lights (brake and battery) came on. He just swapped in a new motor prior to the event and forgot to tighten down the tensioner on the alternator.
Wait...maybe I'm missing something, but how will removing the wiring for the brake fluid level sensor cause the light to not come on for low battery or alternator voltage?
Either way, it doesn't matter. I am leaving it hooked up. Although in all honesty, by the time the light comes on, the brake pedal would go to the floor, would it not?

I believe it is designed to let you know when the fluid is low, not when it is gone.
I had mine come on when the resevior still had some left in it, but was below the "Low" mark. The brakes still worked.

Ah...right. Maybe one of the more useful "dummy" lights then, eh?
I actually had this come on in my ITR once, but it was a false alarm because the fluid level was sufficient. Meh. I'm going to keep it on the S13 though. But the ambient switch isn't quite so lucky!
It comes on before the fluid is low enough to cause a problem. When the fluid level is barely too low, the body pitch and roll caused by acceleration, braking or turning will cause the fluid to slosh enough for the brake light to come on. It's most noticeable under acceleration when the nose of the car rises, causing the fluid to slosh towards the rear as the front of the master cylinder rises.

Good call, C-Note. That mighta been the issue, except the light didn't go off until I shut the car off and restarted it. Probably just needed to be reset by the ECU after "alarm" condition was no longer detected...who knows?
And I drove the ITR like it was designed to be driven, so the slosh is very possible!
