Servo is fine.
Rebleed and check for leaks. I had a Transit Connect which stopped fine but pedal went down only with servo assistance. Turned out to have the tinyest tinyest hole in a brake line.
Eezibleed system is good. I'd like the find a professional version. Vacuum ones are crap.
I've never had issue with ABS having air inside with the Eezibleed. If you have abs you won't have a compensator.
Just bleed and bleed and bleed. You'll be surprised just as you think yep no air, tonnes comes out.
That eezibleed system is far better than pushing the pedal down IMO as I've had 100% success rate after a corrado didn't wanna bleed when new lines put on, the eezibleed is so much quicker.
