Question for y'all...everytime you flush a 996/7 with ABS, does it require a hookup to PWIS or Durametric? Or, if you get it pressurized, say with a motiv, and don't introduce air, the system stays closed? Soup to nuts, I'm trying to understand how the ABS gets bled. I'm not exactly clear what's going on and why, when it seems some systems require ABS manipulation to flush.

I went with GT3 MC and Booster. Was great for 2 track days. Third day I had ice pedal in 1 (pumping did not resolve the issue, the car slowed but the brakes weren't biting with full force)...twice. The only thing that seemed to work was setting the brakes after coming out of 10 by applying slight left foot braking while accelerating (enough to feel the brakes grab). And even then, I was braking around the 5 board...not the usual inside 3/2ish.

I'm almost positive there was air or old fluid still stuck in the system which worked its way to the calipers or somewhere in the ABS by the 3rd day. The system has been flushed 3 times with Durametric...after reading stuff all over the internet claiming Durametric cannot properly flush the ABS I decided to take it to a shop with a PWIS to see if that would fix my issue.
