If the brake pedal depresses fully and the master cylinder does not empty then it is the master cylinder bypassing.
If the master cylinder empties then the fluid is going somewhere else.[:0]
But I'm sure you would have noticed that.;)

My vote is for the master cylinder.

Did it work before????
If it did how long has it been sitting and has it had fluid in it all the time??
