I pulled my brake combination valve off to try cleaning it out. It was a mess inside and the end button is stuck. This is the cast iron style 76/77 vintage disc/drum. The parts stores around here just say "it's a non-serviceable part" Are these available new or rebuilt somewhere? The only aftermarket version I found would require a lot of re-plumbing to fit.
No one makes those as repro's. Sounds like you have/had excessive moisture in your system causing massive rust. I would be very very concerned about line condition. If you have a bad valve you could have corrosion in the lines. I have some combo valves. Email me direct with your shipping address. GStage1@buickperformance.com
Combo valve This place advertises proportioning valve rebuilding in Hemmings, but I didn't see any mention of it on their website. www.whitepost.com
thanks guys. I cleaned the syrupy junk out of mine and am going to try putting it back in. Must have caught it before it turned to rust. btw I called white post, they can rebuild these.
