Hello, You can tell by the wheel cylinder shape. Stick your head under the rear wheel and have a look at where the brake pipe enters the wheel cylinder. The part of the cylinder that you can see on the backplate beneath the 2 mounting bolts will either be round or a flattened oval shape one is Bendix the other is Girling, but I can't remember which is which. Check it out then go to your spares shop and get them to look up cylinders in their book. You can tell from picture.Girling cylinder = Girling shoes, Bendix = Bendix. You'll probably find the cylinders leaking anyway ( renault being crap ) Renault do a kit with shoes pre-assembled with new springs and cylinders included. Worth comparing prices. Good luck.
