69 k20 brake issues

[tinman_local2]

My 69 k20 with manual brakes is giving me fits. I've replaced all wheel cylinders, one front brake hose(passengerside), and bench bled the master cylinder. I don't have fluid at the drivers side wheel. Only brake that works is passenger side front. I've got decent fluid at the rears, but still no good brakes. The drivers front has me baffled as to why I have no flow of fluid. Pedal has a lot of free play, too.Maybe plugged hose?? Any suggestions are welcome.
