The engine is a Vauxhall not a Ford

Orange is the vac hose connecting the servo to the plenum (both tight)
Blue is a feed off the main vac hose into the vacuum box
Green is the feed from the vac box into the plenum solenoids


Highlighted in red is the take off for something I've removed (EGR/secondary air, don't remember which), I've put my finger on the end and it doesn't seem to make a difference




When removing the vac hose from the servo you can hear a hiss for a second which suggests a vacuum was created when the hoses were plumbed in, when the main vac hose is removed the pedal is hard and does not operate the brakes, when it is attached the pedal is soft as sh*t

Help!!
