Caught it early with no lock ups, but my rear pads are gone and my rotor now has a noticeable ridge in it. As others have reported, the rebuild kit is on back order with no ETA. I've not dug into an SMC so I'm not sure how it all works yet. Can I take the thing apart to clean/lube or something in order to get it working in order to buy a little time? I hate to park my bike because this kit is on B.O. with no ETA.
