Thanks all, yes yes.... very lucky. Love that gate. May buy that gate a present.

The car just went in this (Tuesday) morning so I don't know any more just yet. To answer some qu's I was using Motol 600 and Hawk HPS pads. Yes... I know I shouldn't have been pushing those pads hard and probably not tracking them at all, especially with the supercharger, but they were what I had at the time, and they were only one track day old and one month into their lives. It is also possible that I didn't give them enough time to bed in initially, and I didn't visually inspect to make sure the transfer layer had gone across.

The failure happened only about 4 laps in to the third session of my day. Also there was a break for lunch and an excursion to get fuel before that third session. FWIW the pad wear sensor didn't go off until after the spin.

Yes, there were signs. And I wasn't ignoring them, I just didn't realise how serious things were getting. There were signs earlier in the day too, but it was really wet for the first session, and greasy for half of the second, so I didn't push them THAT hard, although both of those sessions were a little over 30 mins each. I think lucid's comments about an IR gun are spot on and that is on my list, along with being more proactive about my brakes and generally being more cautious about things I already know may not be up to scratch.

I don't want this thread to turn into Hawk HPS bashing though. There is enough of that in other threads, and because of the bedding in question it doesn't really add anything new to all the chatter. If anything I think this thread is a reminder to be more awear of your brakes in every way you can, and also to make sure you have exit plans for all corners, especially the ones you are going into fast. Knowing I could go through that gate and being able to accurately visualize that part of the track before I got there allowed me to plan and I believe saved my ass. Being more proactive about my brakes would most likely have stopped the whole thing happening in the first place.

Have been very interested reading all this discussion and will have to read it again to digest. In reference to Hack's levels I think I would be around "Beginner/Intermediate to intermediate".
