Does anyone have experience with a a front brake caliper rebuild on an LC bike? I feel/hear a click when slowly pulling of the front brake lever of my '13 GS wethead. If I put fingers on the right brake caliper I can feel the click. I suspect the piston is sticking or I've a bad seal or something like that. In searching the net I've not found anyone who's re-built LC front brakes nor have I found a front brake rebuild kit. Perhaps my search-fu is weak. The beemer shop does have a kit but their site claims it is for '05-'12 bikes. I'd appreciate hearing from anyone who has torn into their front caliper. Any issues or words of wisdom?
