Brakes won't stop my Valiant 100

Facts.--- 69 Valiant 100 6 cyl auto. 9 in manual drums all around.--- What we did--- New drums all--- new wheel cyl. all--- new pads all--- all new clips, springs, all hardware to hold the brakes together.--- new front rubber brake lines--- New master cyl.--- only things not replaced All brake lines--- rubber brake line piece by rear axel--- and the distribution valve--- All 4 corners bled out.--- I have the exact same hard to stop brake system that I had before I replaced everything. PLUS hold on I took it to a shop to make sure it got done RIGHT. $900.oo dollars labor and no brakes. There scratching there heads trying to figure it out and are willing to help. If we only knew what to do. And I still have to rebuild the front end. Gotta have brakes first.
