Where to start.... When you bench bled the master, was it delivering good fluid flow from both ports? Does the master cylinder return all the way back when the pedal is released? If the master is not returning fully, it can not refill the cylinder because the port is still blocked. Be sure there are no leaks. The current supply of new fittings, hose connections, and lines don't seem to seat as well as the ones from a couple years ago did, you really need to crank the new ones tight. Recheck every connection, look for even the slightest wetness. Is all the air out of the lines? These days, bleeding brakes has become a pita. Unfortunately, these days, "new parts" does not mean the parts are good. Lots of defective new stuff out there. If all else fails, you will need to check brake pressure at each connection to find out where you are loosing the pressure. Good brake parts will force a finger off the fitting under pressure, if you can seal a fitting with your finger, you have located the problem. You will need to start at the master. Gene

is your master cyl on the fire wall or under the floor???
if under the floor,,you need residual valves to hold line pressure since the calipers are now higher then the resoviour,,,( MASTER )

usually,,those brass washers on the calipers cant be reused,,,and most require 2 washers one on each side of the hose fitting,,,
so it would be bolt,washer,hose end,washer in to caliper,,, let us know how you made out

I've noticed that reman calipers come with new washers that are too thin to work, the rifle drilled bolt bottoms out well before the washers seal. PepBoys used to carry a selection of copper sealing washers.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Don't feel to bad about putting the calipers on the wrong side [ bleeder on the bottom ] seen it on here a number of times, your right , it's hard to bleed the air out down. Normally need to get new washers each time there removed, most auto parts stores have them.
it's ok to butt heads, just don't do it with a butthead
