996 brake issues

Need some advice. 996 carrera 2 w/ 20k mi. I had the brake fluid flushed last year w/ ATE blue ( independant porsche shop). Pedal was slightly soft at the end of DE track day after this. Bled the brakes w/ motive bleeder. No change on next track day. Changed the pads from stock to Hawk HPS and flushed brake lines with 2 liters of ATE/ bedded pads per recommendations. Pedal was firm on drive to track although initial bite of pads was not too good. Pedal travel increased after a few laps on next track day and brake were very soft/ very little "bite". Next day, brakes are ok on the street but not as good as stock. Is this a poor pad choice? Glazed rotors? air trapped in ABS?

I use the car for local spirited drives and track days. Not a daily driver. Considering upgrading to a Hawk HP+ or Hawk HT-10. Anyone have any experience with these pads or any others for good track/ acceptable street performance?

Any advice appreciated.

Thanks for the reply. I've done alot of research and here's my plan:

1. Resurface rotors ( they look good but some very mild surface ridges)
2. Stainless steel flex lines
3. New Pads (probably EBC yellowstuff- was thinking Hawk HT-10 but the HPS experience has left a bad taste and the yellowstuff pads have gotten nothing but good reviews at a similar price and temp range)

Then I will bleed the brakes again. If I still have any issue, I might consider changing the mastercylinder and go to the dealer for a bleed with the ABS valves open.

Wish me luck!
