Ah so it is! We spoke at the end of the day just as we were all packing up, sorry I forgot your user name…
Did you get to bottom of your brake issue?
Yes, I think I did thanks. It’s a little bit embarrassing - basically I put a bit too much copper slip on the wheel bolts when I changed the wheels over the day before. It combined with the brake dust to form a gunk which coated the disks and filled the holes up gradually through the day. I think the grumbling towards the end of the day was a result of overheating. Anyway, I’ve cleaned them up and poked the holes clear again and everything now seems fine, although I won’t know for sure until the next trackday.
Did you get the LHD fixed seat runner installed mate?
