Brake master cylinder

[Enoch]

Hi again peeps. My sierra had ABS so I need to get a non ABS master cylinder. All the ones I have seen so far don't appear to have the push rod with them, yet reading the book all the evidence seems to suggest that one is required. Can anybody throw any light on this? I think in the original car a pushrod went to the servo then the servo had something that pushed in the pistons in the cylinder Should I be looking at a different master cylinder?
Your thoughts would be appreciated, as always.
