Paul Hi - Thats a heck of a lot of money for discs and pads - they can be bought for around 65.00 for the whole kit. Take a look on the net or ebay - if you can get to Newark with the car I will fit them for free. You could still drive the car if needed (with great care) as the damage has allready been done.
Ive just put new rear discs and pads on mine about £40, but I know the fronts are a bit more money. Let me know if you need any help!
Cheers
Steve
