I have put new front wheel cylinders on this old car that I am working on, and completely drained the lines and rear cylinders, and put new silicone fluid in and bled them out twice so that I have good strong holding pedal after sitting for 20 minutes. After three days sitting the pedal has gone soft again. I have triple checked for leaks but have none. how is the air getting in?

I suspect there is still air in the system, or the drum brakes have not adjusted properly.

What happens, there is a residual pressure valve in the master cylinder that holds slight pressure on the lines when the pedal is released. Then the pressure slowly bleeds off, giving a soft pedal again.

Check the adjustment on the drum brakes again, try bleeding them some more.
