Rivet size for hand brake

[milesdzyn]

Need to pickup some rivets for the hand brake, anyone know what length they are? I was guessing 13-15mm, but hoping someone knows for sure. I think they are the same diam (5mm,3/16") and are the semi-tubular kind, as used on the drum brakes, which are 10mm long. Don't need them right away just want to package them up with the replacement hand brake liners for later use.
