Replaced master cylindet, front brakes rear brakes rear cylinders, frobt calipers, and front left brake hose along with brake line from valve and line that crosses to passenger side. Bleed all lines but still have the pedal going to the floor, spent hours bleeding system pedal travels to the floor fluid srill comes out of lines and pedal will slowly travel back up to starting position.tested brakes with truck not running and then while running same result.anyone have an idea of what maybe the cause?

 

did you use a pressore bleeder? did you bench bleed the master before install?

 

Bench, filled up with fluid used adapters and stuck hoses into fluid to create hydraulic pressure, kept doing it till no air bubbles were present

 

Did you follow this procedure? http://dodgeram.org/tech/repair/Brakes/beeding.htm

 

I started with the master, then went to rear wheels, opened valves and had fluid. Then went to front and had fluid. Truck does not have abs.

 

So are you doing two at a time? Sounds like you have a leak...

 

If not a leak, did you disconnect the brake pedal to the master cylinder when you were changing things out? Seems like it should be something simple.

 

No disconnect, just took the 2the nuts off the master cylinder and off it came. I will pull it off again and check the push rod .
