well i was tightening my chain and doing some normal maintence around the bike, then i noticied on the inside part of my brake disc (2003 so hydrolic) that the brake disc had brake pad debri like smoldered on the disc, the outside looks just fine but the inside muct have been worn away, the inside brake pad was worn to what looks like GONE and the outside once again is just fine, im hoping and assuming that i put the brake pads on the wrong sides so they wore wrong, if this has happened to anyone else or if anyone has an opinion or something that can help please post thanks.
