These are all available from your local Renault dealer. However, to save some money, try your local Motor Factor first.
The rear brakes were either Girling or DBA - you'll need to check the make before ordering. If you fit front discs, always fit new pads at the same time. Front calipers can either be DBA or Girling, but they are usually the latter.
If you buy your rear shoes from a Motor Factor, buy the fitting kit from Renault as pattern shoes rarely come with the kit.
