John, I respect your contributions to this board especially in the TF area.
I will question why you want to eliminate the self adjusters

back in the day it was a common place thing to do, much like disabling an automatic choke and going back to a cable/manual choke. In my later years and better understanding of both systems, they work great when set up properly with the correct components. I believe that the changeover occurred due to the mechanics not understanding the "new" technology back in the day. They wanted to do what they were comfortable with, IE: mechanical adjustments.
Automatic or new "technology" was new and has to be understood by the person working on it.
With respect to brake system self adjusters I have probably rebuilt in excess of 500 systems in the last 10 years with no issues. So why change to manual ??? DUNNO??? just asking and thanks again for your contributions
