Thanks Mike for the insight on newer mechanics, it is true to the core. I asked some about my problem, and they could say is 'You don't have disk all the way around'? I have 3/16" brake lines and 1" bore MC, I will try and find a MC with 1 1/4" bore that will support 1/4" brake lines with dual bowls. I will still use the 3/16" line to the rear since I know they are working correctly. I tried a residual valve in the front line, same results. I did find one MC that has 1 1/4" bore and has one larger bowl that the other, large one for the front with 1/4" lines and smaller one for rear with 3/16" lines, think that will work?
