On Friday I picked up my new master cylinder:
As you can see - it's for Fiat - Uno/Panda.
Delphi LM70023 -19,05mm bore, 3x m10x1 outputs. I hope it would be OK for my all-disc setup... (19,05mm bore is suggested by "locostbuiders" to replace standard Sierra 22,22mm master cylinder)
Input fittings are "extra" from my buddy as I plan to use external brake fluid reservoir.
It costed about £12... so one of the cheapest master cylinder on the market
