I've had pads go on a mountainbike rear brake during sustained braking on a 20% downhill (in Cornwall) going about 40mph... so guessing it was the heat build up that caused the bonding to fail and the pad to shear away from the backing. A different situation entirely and I only realised it had gone as lever travelled too far and there was a huge screech that came from the metal on metal at the back. Rotor was ruined and it shook me up enough and that was only on a mountain bike.

Looks like you stayed relatively cool and controlled it well after the initial couple of seconds of realising what was going on.
