Low brake fluid - No obvious leaks, NEW QUESTION!!!!! HELP! Options

[slickr]

So I was driving the car for the first time in a week or 2, and the brakes felt a little funny. Also smell something like an "electrical fire". But no smoke or anything. All other fluids seem to be fine.
The very top right container next to the diagnostics box is low (is this brake fluid?) and My master cylinder next to that is low. My car is garage kept, so I would see obvious drips, and none are there . Not sure what this could be, does the fluid level just go down after a while?
thanks

I am thinking you guys are right .
The brakes just felt a little funnny, idk how to explain it maybe a little softer? No pulsating in the pedal like rotors (i believe that would mean rotors)
But anyway took it out a few times and only gotten worse (nothin extreme) but as soon as I let off the gas at any driving speed, the car slows down ALOT! more than normal. But it doesnt seem to necessarily pull in one way or another.
Just driving around the PC parking lot, as soon as I let off the gas (only doing 10mph, clutch in while stopping) the car barely moves another 5 feet before it stops its self. So I think you guys are right.

I am not too familiar with brakes, I do know how to change rotors, pads, calipers. But idk how to know if they are bad.
The outside pads in the front I can see, and the are still there, but seem to just about touch the rotor when the brakes are not pressed. I dont know if that is normal.
How do I know if its the front or rear brakes? I dont think either have been changed in some time

edit: also no obvious sounds of "metal to metal" does this maybe mean that the calipers freeze up?

thanks for anyyyyyhelp, i really need it
