67-68 Balance (proportioning) Valve

[Doc Hubler]

Here is a schematic of the balance valve. Essentially 67-68 were the same (different part numbers). If you go through your brake system, you need to go through and clean these out. THe spring is highly compressed, so you have to have the right tools.

I have a 1968 Balance Valve that has been completely gone through with mounting clip for sale if anyone is interested.

Are you an engineer, Doc? I like your schematic. Clearly not a GM diagram.

Hi Doc i would be interested in purchasing that valve -- also do you have a spare distribution block (or a part no.). Rds, Thad

I can sell you the balance valve -- it's ready to go -- all clean and put back together properly.. The distribution block must be obtained from a parts car. Perhaps John Dorcey would have one. You'd go through it and clean it. You'll have to drill the hole for the bracket that goes on the frame (actually 2 holes I think since one is a tab that keeps the unit from moving).

The owner of the shop restoring my car drew up the diagram, and he said to share with everyone.
