Re: brake proportioning valve= no reset?

I just installed front disc brakes complete with mc and booster on my 66 k10. Kept the rear drum. I installed a new proportioning valve complete with new lines and bled the system. My front brakes grab great but the rear brakes are locking up real easily. My pedal also feels kind of spongy. Do you think I might have a similar problem with air in the system or having to reset my proportioning valve?
