When I was riding last I fried the rear brake pads, since then when I got ready to tear down and replace the rear wheel bearings I noticed that the rear brake rotor hub moved slightly from side to side while the caliper was still in stalled took caliper off and the hub moved freely from side to side. Is this normal?, if not what do I do to keep it from moving? Thanks for any help. I have a 94 Yamaha blaster
