Default Vacuum brake booster unit- Need some help

Recently I replaced the manual brakes with a vacuum brake booster unit and master cylinder combo. The feeling when I push the brakes pedal is good but then when I release it does not return or returns very slowly.
Any ideas what the problem is?

There is a round return spring on the shaft that the pedal pivots on. Mine was broken and a new one fixed the problem.
