confusion over distrobution/proportioning block

Older pre 71 A body with KH Used as well. My 69 does.

Pic posted in the link of the first post is correct 71 up. The “Texas valve was added to the distribution valve. Not the best setup if using aftermarket components. Loosing bleed is another issue entirely. Could be leakage or could be a poor master.

That B-body illustration shows both a proportioning valve and a metering valve. The latter was never used on factory a-bodies.

My question revolves around the distribution block, Inline tube calls it a distribution block but Dr. Diff site calls a similar item a proportioning valve (Mopar 1 Piece Proportioning Valve). I can’t figure out if these are one in the same or if the inline tube one is actually a distribution block and Dr, Diff’s is a proportioning valve.

Do you understand now? They are both combination valves. They appear to be the same. The application information is not quite correct with respect to dates of use. Don't believe me 'cause I typed it here. Go read what Chrysler printed in 1970.

Pirate jacks sold me this setup and said i had to have both and the master had to be changed too. Has a small resivoir up front. I had quite a few leaks everywhere that were minor but caused the same issue. Very hard to notice them. I also had to add another porportion valve in there for the front like the e bodies

Please go read Chrysler's introduction to Dual Hydraulic Brake systems.

and then at least this section about the proportioning valve
