Hello Macaroni
Do you still have any wedges left over from this thread....? seems that I have a couple of different wedges on mine, and would like some input on how yours look.
If you read my brake overhaul booklet, you will find the Renault part number for the rear caliper complete wedge and spring kit. It has four new wedges, the 'R' clips, the correct anti-rattle springs (as well as the wavy copper type for those cars that use them - not the Murena) and even the caliper to frame springs. All this for around £28 the last time I bought some. So they are easy to get!
