Haven't any of you seen how fast cast iron rusts it its set out in the environment without some kind of finish on it?  Especially if it gets scratched up (like if you piled a bunch of them into a container for shipping).  Rust forms in about 2 days in a moist environment.  Wouldn't do to have rust showing up on a car fresh off the shippers trailer when it got to the dealers lot.

I don't doubt they're painted black. The photo stovebolt posted just looked like a rendition to me.

Rendition theory buster!

Theory buster? Just a comment that I thought it looked like an artists rendition. Not an accusation etc...

I'm in the "painted black" camp. However, and no offense, I know plenty out there prefer rust, er, patina.

Whatever cheap, thinned out black paint they shot the parts with would have soon surrendered to the harmful effects of brake fluid. Theses cars are pushing 50 years old.

A question about the Production Parts List above: Is item No. 25, Part No. 5452322, the brass check valve seat? For cars with front and rear check valves, is the part number the same? Thanks, Joe.

Yes, it is - the machined cavity BEHIND the seat contains the check valve and spring on drum brake systems.

Thanks John. Are both front and rear brass check valve seats the same?

  If you are referring to the brass seat itself that is extracted after drilling into it, they should be the same for F&R.
This past thread shows a replacement I found for mine. This is for a 5460346 MC so the size will have to be measured against what you already have. I suspect they may be the same however being the MC was mass-produced.
