I used a stock pedal attached to a bracket and dual chamber master
cylinder supplied by Heavy Chevy. They have the bracket made. They
scratched the part number off of the box of the Wagner master cylinder,
so I don't know what it was from.
The new bracket mounts to the holes used by the original master
cylinder.
I didn't use a proportioning valve. I had a friend watch me make a
number of panic stops in the local high school parking lot and the back
wheels lock up just before the fronts do with no load (my usual
configuration) in the bed and my "moved to behind the rear wheels" gas
tank half full.
I also did not install relief valves, although when I run out of other
things to do to my truck I think I will. There is quite a bit of pedal
movement before braking action begins and I think that adding these
valve would help.
The change to front disks and the dual master cylinder is the best thing
I have ever done for my truck. It stops straight and quickly.

Bill, could you describe your pedal set up as well as the cylinder
and bracket positions and any info and experience with proportioning
and relief valves. Brands, suppliers and whatever wisdom and/or
insights you have regarding this procedure would be appreciated.
I plan to use the non-power assist system you indicate you are using
but things don't seem to line up exactly so I suspect I must be doing
something that isn't kosher.
Do you have any photos or perhaps a schematic sketch?
