Hey everyone,  im going through parts that need restored still and Im needing to restore my original brake proportioning valve.  How would you guys restore yours to a near OEM finish/look? Or who would you recommend sending it out too?  I'm in Alaska, and there is no plating companies here, so I am trying to see what I could do myself, but if I need to send it out, I will.  Thanks!

I think they are solid brass so a soft wire wheel should make the outside look like brand new.  You just need to clean and inspect the insides as best you can.

Good Question:

So there are company(s) that re make these.

However, their are also reports/feedback that they didn't work at all or very well.

I sent my set up to:  http://www.theramman.com/

He re built mine and it works perfectly.

This is an item that will experience some lead time till you get it back.
So if your on a tight schedule, then it may not be the best choice.

It took me 3-4 months. Which isn't bad.
My fan clutch took a year. My steering wheel is out right now for 6 months till I get it back.

Like Cody said, they are solid brass:

!) Remove the Brake Lines
2) Wire wheel the Brake Lines
3) Wire Wheel the Proportioning Valves (you can use a soft brush or use light pressure with a normal wire wheel on a grinder, it cleans up really easy anyways)
4) Blow out the Proportioning Vales & Brake Lines with light compressed air
5) Polish the Brass with some Brasso or Nevr-Dull
6) Put it back together the same way you took it apart

That's how I did mine 20 years ago and they still look like brand new

I don't have a close up right now.

I'll try and take one and post it tomorrow, it's -38 Celsius here today and my garage isn't heated. Too damn cold to go outside, but it's a dry cold, yeah right it doesn't matter when it gets lower than -25 Celsius, cold is cold.

I clean mine up as well. It's pretty easy to do as long as they are working properly to start with.

Here you go, braved the cold.

Still looks pretty good considering I restored the engine compartment around 1982-83.

Thank you for braving the bitter cold.  Its only 30 degrees here in AK right now

Topcat. Who did your fan clutch ?

He was out of Florida and from what I heard he retired.

Tony auto parts makes new one's.

If it had been sitting for a few years, I would send it out or re build it.
I recall mine had some green goo inside which was a sign of parts corrosion perhaps?

Earlier brake DOT was known for water absorption.

Been sitting for awhile.  I think Ill give it a shot myself, see how it goes.  I need to find that rubber grommet that is on it
