Technical tempra brakes

[wombat]

Help! I'm new to this site, being an Audi owner, but my daughter has a Tempra diesel (turbo super sport wagon!!!)and it seems as if the servo is to blame (brakes butr with a VERY heavy pedal)Problem is, after poking around under the bonnet I can't locate the connection between the manifold and serov, obviously the first suspect. Anyone out there willing to help an outsider, (with family connections)
Cheers, Howard (wombat)
