Fiat 1500 Cabriolet Brake Servo - HELP Please

Hello, according to the owners manual, my Fiat 1500 Cabriolet (118K) should come equipped with a brake servo. And mine has no such thing...

I have found out that Fiat used a Girling Mk2 servo, and I have located one.

BUT I have no idea where it is mounted and where the vacuum is taken from.

Anyone have a 1500 Cabriolet that has a brake servo installed that could share pictures and info with me please?

Thank you

Henry

The servo on mine was remote and mounted forward low on the drivers side, almost to the very front of the engine compartment.
I'm sorry I couldn't find photos. You should be able to see the mounting tabs, if I remember correctly there was a structural member there with the mounting tabs on it. Look just behind the left head light but not in the fender, in the engine bay.

Curious as to why you'd want to go back to the booster. Originality?
In my experience cars of that weight don't require much effort and I like the unboosted pedal feel.
For example my S1 Fulvia was "updated" with a booster from an S2 but I prefer the unboosted brakes.

That is one good question!

For some reason I assumed it would brake better, but now that you mention it, the current braking is not bad at all, and if there is no real improvement, I might as well save me the $1,000 + this is going to end up costing. Originality is not really an issue with this car.

Compared to my Fulvia S2 the Fiat doesn't brake as well, and I thought it had to do with the booster, but you suggest otherwise....

Life was simpler before your message

I didn't mean to complicate things.
I found it took a lot of effort to get those (beautiful) rear brakes properly adjusted. I had a hard time finding wheel cylinders so I used some from a Fiat 131. One of the holes in the backing plate had to be slighty enlarged if I recall correctly.
Another I thing I've found a few times in old cars is even though the rubber brake lines look fine they can deteriorate from the inside so I always replace them all as cheap insurance.
I'm not sure whether or not the 1200 were boosted but maybe there would be a slight difference in master cylinder size. Chris Obert would know. A larger master might braking easier.
Boosters really only change pedal effort so if that's acceptable then I would look else where in the braking system before I spent the $.

Nice taste in cars by the way.

Thanks, I was joking about the complication

I also had rouble setting un the rear brakes, and that really affected overall braking, but now it's fine and total brake experience is quite good, so I might forget about the whole booster situation.

It bakes better than my Giulietta for sure

Thanks on the compliments on the choice of cars...
