I recently flushed my brake fluid (ATE Super Blue) and now I'm getting either the BRAKE indicator or the brake fluid low warning in the text window when I brake or corner hard. The fluid level is fine. What sensors would cause these warnings? Is it just the sensor in the reservoir or are there others? I used a Motive Power Bleeder when I changed the fluid. I'm pretty sure we used a low pressure 10-15 psi but I would have to double check with my friend who was in charge of that.

I was sure of the problem until I read that you have a GT. My car was doing this and I had no idea why. It turned out to be a leaky slave cylinder.

I realize you said the level was fine, however these cars seem to have an almost too sensitve threshold on sensing low brake fluid. I would try topping it off just a touch, and see if that does not correct it. Also check the wiring to the sensor.

Also, if you checked the level right after driving, the fluid will have expanded due to heat, thus making the level higher than it really is.

Take your car out for a nice drive and check the level RIGHT after you turn it off. I was having the exact same issue. Filled it to the line while its hot and boom...Issue resolved.

HA! Wait til your slave starts pissing brake fluid on your clutch.
Not if it will, but when it will.

+1 For this. Had the same issue.

But I am still "waiting" on the dreaded slave cylinder to get me

Yea, I had that problem, added a tiny bit, and gone.

Looks like adding fluid was all it takes. I guess it prefers to be 3/4 between min and max instead of halfway. Thanks for the help guys.

I'm facing a problem "similar" to this, but it was on the engine coolant.. The red warning triangle comes on upon hard acceleration, and gives the warning message "coolant low, stop safely". Same problem fixed with a top-up though.
