I'm converting my drums to discs off of a 75 Dart. I picked up the upper control arm, spindles and proportioning valve. Can I reuse the proportioning valve? Not sure if they have a life span.
Nope, they don't wear out.
And, they're not even steel, so the only rust in them will be deposited from the brake fluid carrying it from other places.
They do plug up from all the crud in the lines, but if you clean it out well it shouldn't be an issue.
I am in the process from converting from 4 wheel drums to 4 wheel discs. Based on my research, I wouldn't stick with an old prop valve. I'd recommend getting an adjustable prop valve, like this Wilwood I picked up. In the long run, I think you'd be better off, especially if you route all those brake lines and you get a car that locks up the rear before the front. http://www.summitracing.com/parts/wil-260-11179
The outer housing might be brass but all the internal stuff "ain't." It's a high pressure control valve of sorts. Anybody thinks something like that can't wear out is kidding themselves.
These guys have the kit and here's the instructions to rebuild.

Its brakes ! Damn people I hate to loose my religion on Sunday morning but...
Here's the very first thing one is taught in brake school. "Everyone is better off with a vehicle that wont go than a vehicle that wont stop".
To the thread starter... You haven't questioned reusing the master cylinder, wheel cylinders, fluid lines, from the donor. Apparently you are renewing those.
I wont ask why the proportion valve isn't considered the same.
Do this for us... Look in any factory service manual for instructions on servicing a proportion valve. You will find only that it is not to be serviced.
I'm sure your next question is, "So why does someone build and offer a kit with instructions ?" Short answer is "If you build it they will come".
Better answer is, The same reason someone built a solid state regulator and then told owners all they needed to do was bend a little thingy. They want your money and nothing more.
The internet is like a horse stable. The chit is dropped there to stay. No way to clean it up. Anyone who wishes to dance in the chit need only to google or ask in a public forum for the appropriate tune and dance steps.
For 6 years I have taken others by the hand and led them safely and quietly around all the chit. They came out the other end of the stable to carry on, nothing less than happy moparing ahead. That was/is my only goal. It stems from love for these cars and their owners, not pictures of dead presidents.
Now ending this sermon
You have 2 options, forget you ever started this thread and buy a new proportion valve or.... dance.
Yeah I knew I would be flamed. Your opinion of my comments is not relevant to the question. You wont generate an argument with me in this members thread or anywhere else. Sorry
