Replaced parking brake cables now problem

[SRT-440]

My 70 Satellite didn't have a parking brake cable so I bought a full kit from Inline Tube (which is a nice kit). Installed it and all the related parts inside the drum that was missing..adjusted the pads, and now my brake pedal goes to the floor and barely stops the car. I didn't remove any of the brake lines..so I'm assuming something is out of adjustment?
When I push down the parking brake pedal it does stop the wheel from moving..but, when I release the brake, the pedal doesn't return to the original position and I have to physically pull the pedal back for the "brake light" to go off. Is this all connected or separate issues?

Sounds like the pads are too far from the drums and never really making contact.  (?)
