A glazed pad looks more like this:
You can see the large shiny patches on it. I seriously abused these pads, braking way too hard on a track with very heavy brake zones. I actually used them for another weekend after trashing them, mainly because of pandemic year schedules and budget. They still had 9mm of pad on them, so not totally gone.
They probably were down 20% of braking capability from new, but I could still easily ABS lock my RS4's if I wanted to, and they worked well enough I set personal best times at the track.
I got a set of PFC08 for this summer (can't wait to try them!). I've been curious to see how you did with the PFC11 in the front. Considered that, but decided to go 08 all around, based on several people in my club using them, and the supposedly shorter wear time on the PFC11.
