Brake Proportioning Valve
Looking for some info on alternatives to replace the seized up prop valve on my car if I can't free it up.
The FD P/N (FD04-43-9Z0) is no longer available from mazda. But I did find this info on a spec miata forum:
Notice how the '94 ABS shares the same FD P/N so I'm wondering if say a '95 miata prop valve would work? Anyone have any input?
Thanks

Well I looked up this stuff the other day when I was looking at Master Cylinders and prop valves. Heres what they have on Mazdamotorsports. I have no clue what the differences are.

Or you could hit up Fritz Flynn on the forums, he literally has a barn full of spare OEM parts. I'm sure he's got one bouncing around as well.
I'll also have a look at my Miata(s) to see if their prop valve appears the same (just in case I can't find the FD one). Just keep in mind that the first gen (NA) Miatas didn't come with ABS, though I'm not sure if that would have any effect on the prop valve in and of itself...

FWIW, I just replaced it with a new one. (Mine was corroded and started to leak.)
Keep an eye on that one.
I found mine on e-bay. (was in much better shape than mine.)
Failing that, you might look into aftermarket valves.
I deleted my ABS, so it was just a matter of attaching the fittings/flares and bolting it all up.
If you still want to keep the ABS, I'm sure you could make some splicing hoses/fittings to your aftermarket valve and mount it somewhere convenient.

the 1993 miata uses an NA something something valve,
1994 uses the FD04
1995-1997 Miata uses the F123 valve
