Proportioning Valve Leaking

Post by VizualXTC »

I am experiencing leaking coming from my proportioning valve. I have checked the three brake line connections and it's not coming from those. Does it need to be rebuilt? (Can it be rebuilt?) Is it cracked? Does anyone have any idea where the leak would be coming from, and how to fix it?

Thank you in advance for any help you can provide.

Yes they can leak. There are no rebuild kits for them. The P valve is discontinued.
Yo can take it apart using a bit from a harbor freight security bit set. You might be able to make a rubber gasket from sheet rubber from a hardware store.
