My brake light on the gauge cluster wont turn off, i topped up the fluid the other day and it turned off now its stuck on again, any ideas? Im think its a bad sensor
 
Most likely thing would be a fluid leak. One of the switches that lights up that lamp is a float in the reservoir isn't it? So if the lamp is on again the most likely thing is the reservoir is low again.

If the fluid level is low again, look at the brake backing plates and tires for streaks indicating a fluid leak on that wheel.
 
It’s usually a battery and brake light that I dictates something with the alternator. Sometimes just the brake. I’ve seen just the brake light indicate an internal fault like a “terminal” being bad or the alternator being cheap.

I believe you can unplug the level and ebrake sensor to check.
