Assuming your slave is in the transmission like on my Lancer, open the flywheel dust cover and see if your brake fluid is pooring out. if it is then your slave is bad and thats where your brake fluid is going.
On a side note if the above is the case, i was told with my car, that as soon as brake fluid gets on your clutch your gonna wanna replace it as it will damage it.
Best of luck to you in figuring out your gremlins friend!
