Thanks for all the helpful suggestions. The problem is that the car has a two year warranty and had the dealer NOT felt that I had a genuine case for complaint and replaced all the discs FOC, I would have had to be very careful about what make I had used. I had a Rover 45 V6 for nearly 7 years and dealt with Europarts. I found their spares to be good quality and a good fit something that doesn't always happen with pattern parts.
After some digging I found the following, the front discs on the Jazz are the same as Rover 25/45, so I have difficulty in understanding the justification of the Honda prices. The tyres fitted to certain models of the Jazz it seems are not a common size so expensive BUT when the brakes are multi fit one does expect a better price.
Once again thanks for the helpful suggestions.
