Outer Limits 4x4 Board

hey
my brakes have bin leaking ever since i bought the car but it was just a seep from near the reservoir. started out top it up every month or so, then ever fortnight now its decided to dump the whole reservoir in a day. so i think its time to fix it. what i was wondering is how can i find the leak. it seems to be coming from where the plastic bit joins onto the metal bit. and would the reservoir bit off a vitara fit as i still have a half cut lying around.

need answers asap as its my only car.
thanks anybody who can help.
