Hi, I have a '99 Yam XJ600N twin disc model. Having a rattle which sounded like a loose brake pad coming from the front caliper i took it off to find that an anti-rattle shim is missing. Brakes still function fine but it needs sorting out. Having looked round the web i can't find anyone selling them. Is it worth contacting a dealer? (dont want to pay through the nose though). Help please. Matt
