Brake bleeding- or lack off!!
Discussion
Problem is you have a system full of air, and you need to get some fluid in the system to start with. ideally you would use a vacuum tool to suck the fluid through each nipple, or apply pressure to the master cylinder to push it through - is this easy bleed just a pipe and valve or a bottle to attach to a car tyre to? The latter should push the fluid through without pumping if you open the nipple. Cant say I like the system as you can spill hydraulic fluid very easily if its under pressure. You could just try gravity and leave the nipples open and see what happens.
Did you also change the master cylinder?
It is often very difficult to bleed the rear brakes due to the pressure restrictor above the diff. but the fronts should come out in an unruly rush using an easybleed.
One possibility is that the new servo is not adjusted correctly and is preventing the piston in the master from returning. The fluid enters (and returns) the master through a port that is only open when the piston is fully back. The adjustment is at the ball ended pushrod that pokes into the master cyl.
This is nothing to do with pedal adjustment but just to be sure try pulling the pedal back there should be plenty of free play.
To check the adjustment you will need to free off the nuts securing the master to the servo. If you pull the master forward on the threads then slide it back to the servo face. If the rod adjustment is too long you will feel that the master does not want to go flush to the servo without pushing it. However, now that all the pipes are fitted you may not be able to 'feel' the resistance.
A simple test of my theory will be to release the master fixing nuts and slide the master forwards by about 5mm. Then use the easybleed and try a front brake bleed (don't pump the brakes just bleed). (Also no more than 10psi air on the easybleed).
