In a previous life I worked with subsea hydraulics, if this happened I would suspect a bad non-return valve, or bad actuator. We had much more instrumentation to tell us where to look though.
Ok this may be a bit too much but do you know which lines go to the rear? I dont have my service manuals yet. Also for the propostioning valve is it as simple as just unscrewing it from the front of the master cylinder? Will a bunch of fluid leak out when I do this?? This is a little out of my league.
