Release the hand brake?
Seriously though, if the car has been sitting for a long time unused the clutch plate may have stuck to the flywheel.
You will need to climb under the car and whilst an assistant depresses the clutch pedal (g/box in neutral) check to see if the pressure plate releases from the clutch plate and using a blade screwdriver test if the clutch plate is free of the flywheel.

Can you push it with the car in neutral and handbrake off?
Was the car mobile before it was parked?
Jack the front and rear up and see if the wheels turn easily.

If it’s like the CRS hydraulic systems they are very difficult to bleed. The old one on the blue LX needed the slave to be filled with a syringe or to be bled up off car.
I suspect you still have air in the system. Only other likely options are that you have mucked up the geometry during disassembly/ reassembly or that the pressure plate has coincidentally failed.

If I adjust the rod on the clutch pedal in to sit hard up in the master cylinder I can get the clutch to disengage but the pedal is only a few mm of the floor when it starts to disengage. The rod at the slave is fully wound out. How much clearance should there be between the clutch disc to the flywheel and clutch plate when disengaged? Want to make sure I have enough clearance so the disc doesn’t wear out
Perhaps it's time to reco the master cyl or the slave or both?

Ok, you hadn't said that in your original post. Have you also replaced the clutch and pressure plate assy?
With the push type clutch assy it is normal to have a small amount of free play in the clutch fork when the clutch is fully engaged (pedal released). In other words the throwout bearing should not be in constant contact with the diaphragm fingers.
Rexy may be onto it when he said the pressure plate may have collapsed.
I've had at least one experience with cracked pressure plate diaphragm fingers. The clutch suddenly goes from working normally to a very soft spongy pedal and incomplete release of the clutch making it difficult to change gears.

For $60 it's certainly worth a shot. Just weird how you can go from having a system that works properly, fit a new m/cyl + reco the slave and end up with problems.
