As for the wheel cylinders, if they are not leaking and they push out the brake shoes, they are good.
Can you elaborate as to why I need a proportioning valve, the original set-up in the 86 did have one, I have considered this all along as a possibility to a problem and have posed this very same question on other forums and the suggestion of needing one has been blown off.
I have also considered the master as being an issue because as you say it was made for disks up front, again I have suggested this very same question to others and have been blown off. Please elaborate if you can.
I know what a proportioning valve does, just trying to understand why I may need one here.
