Ok, just figured something out. The self adjuster on the MK3 rear discs appears to work off the handbrake. I assumed it worked off pedal action.
I don't ever use the handbrake on race days for fear of welding the pads to the hot rotors. I just leave it in gear when it's parked up.
I've just worked the handbrake a bunch of times and it's brought the pedal height back up.
I must have worn a chunk off those pads last week
Might have to pull the handbrake a few times before each race.
Pete
