The only thing i can think of is that your master is leaking or wasn't bench bled after it ran out but you are saying it never ran out of liquid.
Just a tip... nobody will tell you this, but the master cyl has the same thread holes as the flywheel bolts... so if you want a quick way to bench bleed it I have a quick way to do it efficiently.
