Are you actually taking the pistons right out and then bleeding the brakes?
I did, and TBH I had far more difficulty bleeding them than when I fitted the new brake pipes last year, I bled them backwards, forwards and sideways to little avail, eventually tying the lever back to the bars overnight did the trick, I got the pistons out using an airline, cleaned them using an old scotchbrite washing up pad and brake fluid.
