Here is a shot of my Left Rear (three piston) caliper (#878) and ebrake with original cable end shown, attached to 3mm (1x19) stranded cable plus some misc hardware.
Close up of ebrake mech. Note difference in cable end attachment from the one listed by Denis of car #1244.
Much closer up:
Misc hardware, cable ends, sheathing. New sheathing shown between two pieces of old. New one is probably 3/16" but is nylon lined. Old ones had no inner liner, just steel....with a black vinyl outer covering. Brass sheathing "adapters" and one new cable end that I got that was used with the "much to large" cable that my guy built this all out of.....clevis pin for end of ebrake cable, and the pulley which fits in the arm/lever at the front of all of this rear cable assy.
I had a heck of a time brazing that cable end back onto the 3mm cable! Brazing certainly is an artform.....! These ends will be tough to find similar. I don't like the steel ones.... If you have your old cables, you can reuse them if you are careful with the torch!!!
Here is a GP view of a three piston rear caliper marked "Fiat-Girling" and was used originally on Fiat 2300S models. Not many were imported to the US, but they were a nicely equipped sedan for it's day!!! Fairly quick change pad design for main pads. E-brake pads are a bit more fussy! These are cast iron calipers.
One other thing regarding cable, was that Nate mentioned getting 2mm cable for the hatch latches and the hood. I measured what my car is currently using, and on one side it appears to have (possibly!) original cable that measures 1.85mm (.072") and the other side definitely has newer 1.6mm (.064") stainless appearing cable.... I like the idea of the smaller cable being a bit more flexible. (Neither are stainless most likely as both are magnetic.
If anyone can post the diameter of their hatch/hood cables perhaps we can see if the factory used different sizes...
Denis mentioned that he had 2mm ebrake cable...but that I hope is a misprint....as it seems too small for an e-brake cable....IMHO.
