Just a guess here, but have you replaced the soft lines as well?  I understand that somemtimes the old ones get flaps of cast off rubber in them that  can act as intermittent one-way valves.  I'm sure someone else will have a better idea.

I dont think it could be the PDWA, though, since both front brakes attach to the same 'chamber' of the device.  I suppose there could be a blockage in only one of the passages coming out of it. 

When you pump the pedal while that bleeder screw is open, do you get air pressure, or is the air static in the line?  I'm just thinking that a 'one-way valve' that prevented pressure from getting to the caliper wouldn't stop your test of vacuuming at the PDWA connection.

I hope someone else can be of more help
