I bought an S13 about a year and a half ago with an SR20DET already swapped, a few things, and I was told a Z32 master brake cylinder. I was looking at the thread in the best of 240sx forum ( http://forums.freshalloy.com/ubbthreads/showflat.php?Cat=&Board=UBB21&Number=67841040&page =0&view=collapsed&sb=5&o=&fpart=1 )and saw which one you are supposed to buy. I got a new chassis, and I'm about to upgrade to Z32 front brakes. I looked at the MBC on the old chassis and it looks like the wrong (3-port) Z32 is on there (from the older Z32s). How can I tell if it is actually a Z32 MBC? Will it still work ok to swap to the new chassis if it is in fact one of the older 3-port Z32 cylinders?

Thanks

And across the back it says:

Is that middle line wet from leaking brake fluid? If so, I'd play it safe and just get a new MC.

I don't think it is dripping or anything, I think it may possibly just be slight seepage or something. This will be going on a completely different car anyway though and I'm sure with a retap and some teflon tape that would be fine with the different lines...

The lines seal at the tapered surface, so teflon tape on the threads isn't going to do anything. It looks like you might have some kind of Tokico remanufactured MC or a copy. My guess is the previous owner rigged something up to "kinda" work which is why it's a little damp around that area (didn't get a perfect seal).

Try removing the middle line and inspecting the flared part for damage. If it's damaged or nicked, then I'd go for a new MC with a pre-installed center flared fitting.
