1999 fiorino 1.7 td

hi i have a 1999 fiorino 1.7td that needs a new brake servo any ideas were i can get one or get the old one repaired , or is it possible to fit one of another car as dare i say it a late fiesta one looks similar ! its a bosch servo , thanks. dave
after reading other postings i may be wrong there is a constant hissing from the passenger side footwell and as soon as you put your foot on the brakes the hissing goes , the brakes work ok , any ideas ????
cheers adve

Did you solve the problem?
The Brazilian made Fiorino uses it's own design brake servo, no other will fit, I'm afraid.
Mine was broke as well some years ago, I had to buy a new one at the FIAT dealer....wasn't cheap at all......
