Title: Fulvia S1 Girling conversion
Post by: simonpen on 03 August, 2020, 04:25:10 PM
Rossocorsaitalia have a Girling (front) brake conversion kit for S1 Fulvias. Didn't think this was doable. Does anyone have any experience of it?

Why would you want to? Properly maintained there's nothing wrong with the Dunlop set up, I've been over the Pyrenees and the alps a number of times, and in 20 years I've never had a problem, certainly high pedal pressure is required, but they have excellent feel.

I agree if the car is used regularly. If not then the Dunlops are more problematical but when used for 100 miles they are very good. The Girlings either work or seize up up depending on maintenance.

Yes this can be done, itís better if you use a S2 21mm master cylinder, the other issue is clearance on 13in rims. I am also looking at this plus adding a S2 servo, I mocked it up and seems to have enough room.

I think my S1 has this modification and it has 13" wheels.
I'll take some pics and try to upload them.

My Fulvia Berlina 2C has dunlop brakes (calipers recently replaced with new units) and non standard servo - see photo

Beware! The geometry of the brake and clutch pedal mountings on S1 cars is different to those of S2 and S3. If you try to fit an S2 master-cylinder and servo you need to make a serious modification to the spacer link tube that goes between the bulkhead and the servo. Somewhere I have drawings to show the critical angles and dimensions for cutting and welding. My advice is donít do it Ė stay with Dunlop!

What I have gathered is that replacing the master cylinder to a dia  21mm and front calipers is pretty much a direct swap and was done in period as the Girling have a much larger surface area. There is another forum where this conversion is well documented.

The adding of the servo was exercise that I wanted to see if I could solve, with it being reversible. So looking at the space and geometry it looks like it can be done, I will need to change the connecting rod where it meets the pedal and fabricate a mounting plate of the right depth, angle and from 2 to 4 bolts. The biggest issue is that itís very close to the steering box.

Thanks for the replies. I shan't be going down this route as the Dunlop system in good nick is good enough and the conversion I saw is pricey. I have been told that the easiest way is to source a pair of S2 uprights and callipers. Not sure why one would bother with the extra hassle of fitting a servo although my S of course has a remote servo already but I'd be happy enough without servo assistance.
