Bad proportioning valve?

did MP message you back?
Yes, they said the dist block and the tool are both GM based and will work together and they did.
In the end, I found I had a leaky distribution block (brass seats weren't sealing completely). So I
looked and looked and so many new distribution blocks have similar issues. I finally found one on
Summit that had great reviews, installed it and FINALLY! No more leak, great pedal feel, can lock up the brakes now.

This is the one I installed.
