Yes, the key was in two pieces, fairly neatly sheared. Thinking back, I did hear a bit of a bang-ette the other day from the rear and couldn't work out what it was. I had an investigatory feel of the brake, thinking it might have been a shoe sticking but I suppose it was the key shearing and I've had drive on the taper until today.
