Hopefully someone has some ideas for me. I have just completed putting in an entire new brake system (lines calipers master cylinder etc) on my 66. I put front and rear DIsk Brakes with a power master cylinder (also new) I bench bleed the master before installing, I bleed the entire system. I get a good pedal when the truck is not running but when I start it and the power booster gets vacum the pedal goes all the way to the floor no resistance. I have found no leaks in the system.
I am running a junction block not a proportional valve, could not running a prop valve be the culprit?
I also had bleed the system with a vacum hand pump thinking that might do it (no luck).
ANy help is greatly appreciated.
