I recently put a table on the dutch forum listing braking distance and pedal force at 100km/h for the Fulvia versions.
See http://www.viva-lancia.com/lancia_fora/ ... 924&t=3872
If you can't read it let me know and I will translate it in English.
I took the data from the Technical Data and Specifications book. It is at the rear of the book.
Is there anyone out there?

Re: Is there anyone out there?
Hi Paul, what do you mean by "front cylinders are marginal" ?

Re: Is there anyone out there?
Georges,
I mean that with the 21/8" cylinders, the wall thickness is very small. This means that if you bore out the cylinders to line them it is easy to crack the casting when pressing in the liner.
I must say however that we did do some at Evolution Engineering successfully.

Parts availability
I got some questions about availability of parts and prices for the overhaul. Here some answers.
I have the Goodridge hoses for S1 normally in stock. These are teflon hoses with stainless steel braided sleeve and plastic sleeve. A special extension is machined from brass to make them fit the S1 without modications. A set of three hoses costs 160 euro including the extensions.
The Mintex pads without vitamin A (asbestos) are € 40 per set of 4. At least I think. Might be 50. I have to look it up.
Overhauling the wheelbrake cilinders is € 100 per cylinder including new seals and dust covers on exchange basis. Pistons for the front are made from ferritic stainless steel (430). Pistons for the rear are made from brass.
Best is to give the callipers themselves and their parts including the parts of the handbrake the same treatment of nickel and zinc plating. If there is rust on the inside of the callipers, the pads will get stuck. Don't neglect the callipers.
In the case of a complete job doing all callipers and all their parts the price is € 1000 per car on exchange basis.
The diameter of a 2 1/8" cylinder is 54mm.
After grinding to oversize of 0,5 mm the diameter is 54,5 mm which is still more than 2,5mm less than the diameter of a 2 1/4" cylinder which is 57,15mm.
The nickel and zinc plating is not easy nor cheap. I use a secret layer between the nickel and the zinc as zinc can normally not be put over nickel. A very large part of the cost is in the preparations. The cast iron is a disaster as it has an very open surface. Brake parts are even worse. There is rust, dust of the brake pads and loads of other contamination. After simple blasting they will be rusty again the next day. The process includes two stages of chemically cleaning, nickel chrome blasting and blasting with steel balls. After which they have to go into the plating process within hours.
For these reasons I have changed from a single nickel layer to nickel plus zinc. Nickel to have the relative hard surface inside the cylinders and zinc to give continued cathodic protection against rust even when the layers have scratches or other imperfections. There are no imperfections on the cylinder walls as they are perfectly clean after grinding.
