I had one on the SD that was a real pita to bleed. The final solution was a pressure bleeder. The pedal still seemed soft with the car up on stands but it was perfect with the car on the ground.

I now get a cap and make a car specific bleeder connection the 1st time I have to bleed a new car. The caps are stored in an old coffee can in the shop and are even easy to find when needed because they are messy when stored any place else.
