No brakes

HELP!

I've Installed the cupra/focus master cylinder, bled the lines but have no pressure.
Pedal going to the floor. I have the 3mm spacer between the servo and the master cylinder.
Any ideas appreciated

Was the mater cylinder new or used? All lines are leak free and bled up correctly? 

It's a salvaged part. Looked good though

It's a salvaged part. Looked good though and used an eezibleed. No leaks and no air bubbles
