Hey SFEBody, what is the universal kit that you refer to in your post? Mfg, source, cost?? It may solve my issues. I have had problems with my brakes on my 70 Barracuda since complete restoration and rebuild. New everything as far as brakes concerned (MC, Booster, lines, drums, components, etc.) I have bench bled the MC, adjusted the booster pushrod to MC, and bled all 4 corners several times. With the engine off, I can pump up the brake feel. As soon as I start the engine, the pedal goes down almost to the floor and braking action is almost nil until I get to the end of the pedal travel and then it is nearly immediate full braking action. Any ideas by others???
