Brake Proportion Valve
« on: October 08, 2020, 00:25:37 »
Does anyone have pictures or a diagram of the interior of the Brake Proportion Valve?

I took mine apart and I want to make sure it goes together correctly.  I lost my pictures of when I took it apart :(.

I forgot to mention the PMB brakes also rebuilds them and tests them on the bench before sending them out.

Can you give us a run down as to what you did to rebuild it, as I assume this is why you took it apart.  They aren't cheap to purchase new so it would be nice to see how you refurbished it.

I had mine done by PMB. They show on their site the valves for the Porsche 914 which are very similar to mine. I asked before I sent mine to them and they 1st replied that they had to check. A few days later they said Send it over. A few weeks later, I received it back looking like new. I think it cost around $150 in 2017 including the plating.

Thanks for the lead on this. I just sent my old valve off to be rebuilt.
