Caliper Rebuild - no brake pressure after bleeding

So yes, I feel stupid even asking this but............
I rebuilt all 4 brake calipers, but left the lines hanging into a container while they dripped. (what I believe now to be a mistake)
Put everything back together and preformed my initial bleed with the ABS cycling the pump with a button.
Then had my wife do the pump and hold technique.
Got in the truck and pedal went to the floor. (of course I had already put the wheels back on and lowered the truck)![Frown](https://landroverforums.com/forum/images/smilies/udbMv2o.png)
Back on the stands now
Went to all four corners using the ABS pump cycling method again - some air did come out but kept going to make sure it was good.
All 4 corners.
Back in the truck, crank it up and pedal goes to the floor. If you pump it, it will build pressure for a moment then back to the floor.
I'm going to do another round of bleeding but was curious of any input you guys might have to offer.
Or names to call me - whatever seems appropriate

Yes, bleeder should be on the upper portion of the caliper.
And yes, letting the system stay open, draining, especially all four hoses...is not the best case scenario. Usually, if replacing or rebuilding...do one at a time and try to minimize fluid loss...and refill as you move on to the next caliper. I use little rubber plugs to incert into hose ends to slow fluid loss. Once all calipers are installed, l bleed until fresh fluid has completely replaced all old fluid.

Two rounds of bleeding with ABS pump and good to go.
Trucks back on the ground and brakes feel nice and firm.
Thanks for the replies.
