Hi When my S3 was having a routine brake fluid change at the dealer recently, they commented that all four brake caliper nipple caps (? I think this is how they described them ?) were missing. They ordered them for me and here they are. They are the size of tyre dust caps - about 1cm wide - and there are two fat and shallow ones, and two more like tyre caps. Can anyone tell me where they go?! Had a look around the brakes but not sure where they go. Help appreciated! Cheers.
