have you checked the vacuum line to your brake booster?

Did the master and booster come as 1 unit? If they are anything like the old Zs, there is a rubber block between the pushrod of the master and the booster - lose that, and you end up with symptoms of improperly bled brakes.

And you bled the master first?

also o back and check all your lines and nuyt's bolts make shore they are tight.

I once used the wrong washer and had the same problem.
