Don't waste your time Bernie, most capris have had their master cylinders sleeved and seal kits are readily available in Aus and are dirt cheap.

Keith, I'm not really sure why Ford would have updated this catalogue except that it does include 8 and a half pages of specific RS3100 parts. No cost to you, Keith.

Current ride:
'83 Mk.3 Capri, 2.8i, 5-spd

Hi Terry,
I'd love to buy a CD from you re the latest Spares Manual inc 1969, 1971 and 1973
Cheers

Thanks  Steve,
main reason for R&D is to hopefully go to 25.4mm(1)" instead of factory 20.64mm (13/16") to get around 20% more braking power, which would not go astray !

piston area is a function of diameter squared so it would be a 50% increase, or in other words a 50% decrease in pedal force required which might just lead to locking up earlier.

In theory to get less pedal pressure for a given amount of braking you would need to change to a  smaller master (not bigger).

how embarrassing.....that's what happens when you answer late at night with one eye on the TV.  So yes would result in a 50% increase in pedal force required.

Interesting article but forgets the booster element all new cars have. Really doesn't change the point of the article though.
For me I had the original booster uprated which simply puts more force out than my puny legs can push and instantly better braking. I don't drive the Capri in the wet but always think about lockup if it was wet. Booster changed to 1:5 ratio by an engineer. Sorry should be put in its own section as off topic.

Excellent bit of education that reminds me what we were taught decades ago. 100% correct. 
 
P10162 for Escorts looks identical to Capri master, and my PBR Books tell me they employ EXACTLY the same
repair/overhaul kit. Brand new Master is less than $200 which is a good price and better than re-sleeving and the chances you take with re-sleeving, such as
1/"sorry, I've lost your master cyl"
2/ "we've never had one leak before"
3/ "you must've done something wrong when you installed it"
4/ "sorry if our re-sleeving is dearer, than a new master, it was harder than we thought"
5/ "what do you mean we've sent you back a different Master?"
6/ etc
Does anyone know if the tube nut ports are same on escort as capri ?
and if mounting flange is common to both ?
and if piston to pushrod measurements are same ?
 
many thanks to all helpers

That excellent article "Pulp Friction" covertly explains in detail that millions of mass produced cars inc Capris, all worked fine for roadworthy standards with the Factory Brakes , so why would you second guess the engineers who got it right from day1 and alter the formula ?
Out of all the modifications/upgrades you could possibly do on a mass produced road going vehicle, the ONLY one they say should be entertained if you must, is to use "SLOTTED" rotors to possibly reduce glazing of the pad surface, from what I gleaned.

The 4cyl Capri looks the same but is shorter. I wouldn't think the whole kit is the same but seals might be. I know you refer to Escort.

according to all my AUSTRALIAN PBR and Girling Books from 1980 thru to 1990, theres NO difference in any Master fitted in Australian assembled Capris, regardless of any 4cyl or V6 or GT ............
(I do see they specify wider rear shoes on V6 1972 than 4 cyl 1969)
..........any comments/ideas re this please ?
