Should I check mine that was purchased from a vendor several years ago? I'm not inclined to open up the hydraulic brake lines.

I did and it did; I don't think anyone's found a brass valve on the market that didn't have the proportioning section. I'm hoping Tom Pryor's efforts change that. I put the steel valve back in.
Bill, thanks for the feedback. I didn't see any marking on the underside of the valve. The marks (cast on the side of the valve) are HJ 04 84 9419. These are preceded by an irregular rectangular symbol that I do not recognize.

Guess I'll get a couple quarts of fluid, do a flush, install the speed bleeders (with teflon tape) and open up the proportion/combo valve when the rainy season ends here in FL. If I have to modify the valve and there's a dramatic improvement in braking I'll report back,

JP
