Curious problem with a p reg 1.8 mondeo, car has sat for 18 months, chucked it through an MOT as the body is rust free and I dont need it anymore, obviously after sitting for so long there were a few issues, front brake judder, rear brakes binding (seized cylinders) and no reserve on the handbrake.

So I put new discs and pads on it, swapped the rear cylinders, cleaned and greased the rear adjusters which work perfectly and bled the system right through with new brake fluid....

The issue is now that I have done that, there is still a huge amount of travel before the brakes actually work, when I get almost to the floor the brakes work great, but before that the pedal just goes straight down, any ideas as to what it could be? has been suggested that the servo has perished away causing the pressure to leak, could this be it? if so is it an easy repair or is it something else?

Any help much appreciated.
