Ford Master Cylinder
 

I have just purchased a brand new master cylinder for a Ford Blitz.
It is made by Protex ( an Australian Company) with a PBR part number.
It is P4572.
I was looking at sleeving my old one, and the piston was very corroded. I took it to a brake shop run by guys that I know, and they found the new one. They said that you could get seal kits for the old cylinder, but no piston.
I can't say how much I paid for it, as I got it for mates rates. You would need to get a price first.
Next, I will see what I can find for new slave cylinders.
