I have a 1993 celica gt 2.2L 5 speed manual transmission and all of sudden every day or 2 my brake reservoir is half empty. Ill fill it up to the top and once again its half empty. I know this because my brake light will randomly come on and wont go out until I fill it up, I see no visible leaks by the any of the calipers nor near the master cylinder. Any idea where my fluid could be going?

Unbolt the master from the booster, check the booster! Start car see if the booster is sucking air from the front seal. If yes it is sucking it out of the master and it's getting burned off in the engine!
I think this is remote, I would remove the calipers and pull the dust boots out to check for fluid leaking past the seals.
