1994 audi quatro

Looking to find the procedure or order to bleed my brakes down. I had a rear caliper lock up via the emergency brake cable lever/actuator on the back of the caliper. It just rusted or gummed up and did not move back on its own. I have not had the car for long, so I have not done brakes on it before which involved bleeding. Any help would be appreciated. I had to pull the piston out because the seal was torn/ deteriorated and had begun leaking. I clamped the rubber line so it would not continue to pass fluid. everything back together. I then started the car and applied the brakes as I started to roll back...to the floor it went but stopped when pressed firmly.... yet no leaking occured...air in the line is my assumption. Hopefully I can just bleed the system down and put the new brembo's and pads on tomorrow without a hitch! No proportioning valve please! Help!
