I just got my new MC/booster setup from ground up today. I installed it a little while ago. I didnt get around to bleeding the whole system, just bench bled the MC and installed the lines. I backed out of the driveway and the brakes feel kind of soft (but i sure can feel the difference in stopping power already) and when i let up on the pedal it takes a while for the pedal to come all the way up and it feels like the brakes drag for about one second.
Does all this have to do with not fully bleeding the brakes? or is there supposed to be a return spring?

Chris,
bleed the entire system. then post the results.

p.s. there is no return spring.
