Brake caliper/master cylinder mix?

I have a rear caliper from a 1990 ZX-11C, and the original rear master cylinder. Will these work together?

Have the ZX-11 swingarm and wheel on my 1980 KZ1000 and almost done, but not sure if the bore size of the ZX11 cylinder is the same as the KZ.

There use to be a website, that I thought was called mykawasaki or something like it. This was nice for part look up. Anybody have/know of the site I am referring?

Try the master cylinder and see how it works.

I have a 96 GPz1100 front master cylinder, 83 GPz750 calipers, 79 KZ1000 drilled rotors, and braided stainless steel brake lines, on my 79 750 twin, and the brakes work great.

Is that "mix and match" enough for you?

I'm using the original caliper, rebuilt, SS line and a GSXR master cylinder on the rear brake of my kz650 with no issues.
