I agree with purple,they must mean brake discs.Please don't tell me you got a main stealer to service the car because if thats their terminology I wouldn't have much confidence in their workmanship.How much did the service cost? Was the bill itemised i.e. can you tell the individual cost of these"blades"
Thanks for that I was vaguely thinking of buying one,think I'll stick with my octavia,not a bit of trouble in two years ownership.I'm a Fiat escapee never never never ever again
