1969 Cross-Ram Z/28

----Although no expert, I agree on the black master. Along with that though is that I have always felt that only the rough casting was black. Any machined area would have no paint. In other words the whole raw master was painted black before it was machined........Bill S

Sprayed or dipped?

My 69 Z/28 with 17,000 miles on it in 1972 had a black master cylinder. It may have started out gloss black, but by then it was faded down to somewhere between satin and flat black.

It was a Norwood cat built in August of 1969.

Definitely not dipped. All the passages would get paint in them.

Sprayed, but very lightly. I have never seen one that had paint runs, and have seen some that definitely did not get full coverage. Gotta remember, GM didn't give a hoot about what that master would look like in 10 years. Just needed to be nice enough to get it off the show room floor.

Here's one on a '69 Nova SS prior to delivery. Some runs, looks dipped to me. If it was done prior to machining there weren't any passages.

you'll get dinged for it in Frederick if its not natural, what can I tell ya LOL. Guess we need to tell the guru's there. I'd love NOT to have to strip my master cylinder

That is true Sam!! There is some we all learn everyday, that's why i like this site, always learning...

You may be correct William. Although from that pic it is difficult to tell if that is a run, or if someone spilled some brake fluid when filling it up. Not saying it isn't a run. Besides, even if the passages were not machined, you would have a problem with paint in the reservoir. Paint and brake fluid don't get along very well.

The finishes I have seen certainly don't look like other dipped components, like the cross member or motor mount stands. I have found dried puddles of paint on those, and would expect the same on something as oddly shaped as a master cyl.
