Jeff-
I've changed my rear brakes twice and I've never had to crack  a bleeder in
order to get
the pistons to retract.

I would not  have cracked the system to change the pads and would have
definitely  started
the car and pumped the brakes to get the rear calipers to adjust  before
doing a full system bleed.

Did you get clean fluid both times  you bled the brakes? No bubbles?

I would keep bleeding- I've had to  bleed the full system twice to get a firm
pedal- the ABS
pump makes  things difficult.

Was this a pressure bleed system or a vacuum  bleed?

I have a similar problem with my 98 A6.
I did pads and turned rotors on the fronts and only pushed the pistons back  
(without opening the system) and the car feels like it lost power assist. I 
have  double checked all the mechanical aspects and everything is as spec. I  
lubricated the carrier pins, and the calipers float nicely as they should. The  
rotors are clean and pristine, and the reservoir is full and never had any  
possibility for air. Pumping the pedal has no affect so I'm certain it is not a  
bleeding issue. 
What could cause such a need for hard pedal pressure?
I don't think I can lock up the wheels no matter how hard I push. They seem  
to do better as they get warmer, but they are not race pads, so I'm not sure 
how  to "break them in".
Could the pads need to be "seated" and "seasoned" or some such, and if so  
how does one do that?
TIA
