Last PCAP SPM event the car ran well, no braking issues, ran a 1:26.019 on Bridgestone Potenzas.

PCAP Day one: Pedal started very firm and stayed firm until last run. A little ABS happiness but the car was stopping around 2.5ish into 1.
Day two: Pedal started slightly less firm than day before. No issues.

Following Track day 2 weeks later: Pedal retained a slightly longer throw and slightly less firm feel as from last time on track. 4-5 laps into session 1 when I had clear track and car had warmed I pushed into one hit the brakes and got some (~3/4 of full pedal) but not enough braking. Upon pumping the brake nothing happened, still had some but not full brake. Pucker-factor was high, but fortunately I was able to retain control and not hit anything. Went back in to check things over, everything looked fine, took it back out. Was mindful of previous event so I backed up my brake point to outside of 5 board. Another few laps, another brake issue. Lots more space to maneuver but never-the-less the braking was not optimal. Brought it back in for the session. ---should also point out that this was only a noted issue in 1. Although, I have a suspicion that it may have also occurred heading into 5 but most speed had already been bled off so it was a non-factor and a bit indistinguishable at the slower speed.

Talked it over with some folks in the paddock, made a phonecall, and reluctantly took it back out for the next session but this time set the brakes with left foot braking while accelerating out of 10, and kept brake point clear outside the 5 board. No issues to report with that regimen. If truly ice pedal, I think it should have occurred regardless of setting the brakes, no? To try and describe what the pedal felt like...It reminded me of ABS coming on but without actually braking.

Just picked the car up with a PIWIS flush. Pedal feels solid, good throw, ABS seems to be less chatty (as best as I can tell on the street, at least)
