Lift the bonnet , lift the triangular inspection flap over the pedals, get a friend to fully depress the clutch pedal while you peek down the hole left by the inspection flap at the three hydraulic connections / 90 degree elbows on the inner wall.
At full clutch travel , my pedal was scraping against the brake hydraulic pipe and had worn through the plastic cover but not started on the inner yet.
With enough time and use I could imagine it wearing through causing total brake failure.
Temporary solution - slighty slacken the pipe nut and swivel the pipe away from the line of the pedal travel then tighten up again.
I am going to ask my dealer for something more permanent.
