R reg 1.9 TD Fiat Ducato campervan. When we got it out of the drive yesterday the brake pedal went to the floor with hardly any braking action. Worked fine on it's last outing a few weeks ago.
On inspection, no brake fluid in reservoir (was there previously!), no obvious leaks, filling reservoir made no difference (I.e. pedal *didn't* become spongy, brakes still crap).
I'm suspecting a master cylinder problem. Does that sound reasonable? Where did the fluid go? Leaked into servo? Any idea of what it'll cost to fix?
