Please help before I kill myself.

I converted to rear disks and now have to pump up the pedal everytime I let off. Hear is what Im running.
68 Vette disc/disc master
front from master to a "T" out to the calipers.
Rear from master into a wilwood adj prop to 85 camaro front calipers mounted on steeltech brackets.
It acts like the new master isnt holding any residual pressure?
What do you think?

Conversion is modeled after this http://www.chevelles.com/forums/showthread.php?t=115940
