Replace Master Cylinder

I am absolutely certain my car is a factory drum/drum car. That being said, I asked this question because when I was looking at re-manufactured MC's (like Cardone), the one that is on my car looked like the ones they are selling as disc brake MC's. So I am not sure whether to just reorder one that looks like the one on my car, or something else.


I'd order one to specify drum. The other thing about drum / drum masters is that they have what is called residual valves in the master. The disc section of a disc master does not.
