Anybody Have a Spare Rear Brake Valve?

[Oiluj]

Looks like my rear proportioning / residual pressure valve is the culprit.

Looked in the classifieds, but no joy.

I can put in a after-market valve, but would prefer to use the correct one. Anybody have one they are willing to part with?

If the valve is just plugged up it can be taken apart and cleaned up. Any aftermarket valve will need adapters and will end up not fitting correctly where the old one was.

It doesn't seem clooged, it's just not working.

Problem is I can't get it apart to check it.. The outer seal is easy. The inner piston & seal won't come out.

There is a place called Rod's Datsun parts (http://www.rodsdatsun.com) in San Jose. He would probably have what you need. Get some Datsun T-shirts too.

Is this valve on the firewall? What year is your Z?

It's a 1972. The valve is just above the rear suspension under the car on the passenger side. It is the brass valve just before where the rear brake line T to the rear wheels.
