Trying to trace a Fiat brake master cylinder

[ColinMcBride]

Hi, a newbie here who has joined the forum for a specific purpose. I have a Citroen 2CV which has been fairly drastically modified and is fitted with a Rover V8, Jag back end, Viva front end and numerous other odds and sods. The brake master cylinder is Fiat.....and has given up the ghost.
I have 2 easy choices, get the one I have rebored and lined....or get a new one. The problem is I don't know what model or even year of Fiat it is out of. The 2CV was originally built in about 1990, so I'm guessing the master cylinder is from the 1980s.
I am attaching some photos, but a brief description is:
Fiat dual circuit master cylinder with number 4336700 on side and then the number 9 about 30mm to front. Total length 190mm from servo flange to rear brake pipe exit. 19mm bore.
Dual front pipes come out on top, 95mm from servo flange, single rear pipe exits at front of master cylinder.
85mm between centres of front and rear reservoir inlets.


I've just been to my local Fiat garage and some specialist motor factors, but have drawn a blank. Can anybody on here help identify what car it is from.


Thanks, Colin.

It's off a Fiat 131, just Google the number.

Apologies for going off topic, but how the hell does that work, lol?

Quite straightforward really. Back in the day I.E. about 30 years ago when custom cars were the in thing rather than chavving up a Corsa or Saxo, you chose a suitable car - usually a Moggie Minor or an old Ford Pop. You then usually grafted on the usual suspects, as in this case, of a Rover V8, Viva independent front suspension & subframe and an independent rear axle off an old Jag Mk2, Mk10 or XJ - remember, this was when the scrapyards were full of what people know as classics now but were worthless then. Result - instant custom car. Check out a copy of Custom Car of that era for more info.

Fair enough. I never went through the chav car phase, lol!

It was sort of the opposite of todays' fad of lowering everything.

I see! For want of a better way of putting it, the trend was to create a wolf in sheep's clothing, rather than the current craze for all show, no go?

Mmm, not really - more like a wolf in wolf's clothing. The car scene back was in two camps, one lot read Custom Car and did crazy stuff like this that looked and sounded good but drove lousy in most cases or the other lot read Cars & Car Conversions and were into rally Escorts, Minis' Etc and did it all properly.

Maggers,
Thanks, I had tried all sorts of Google permutations with the number, but never got anywhere. I followed your lead on the Fiat 131 origins though, got through to Recambio and identified one that isn't quite exact....but close enough.

Brakes now working and project slowly gaining ground again.

Sorted! Let's have some pics of the beast!
