Rear leak at disk

[mmcbiker]

Hey guys I noticed some oil on pass rear brake disc, it looks like it is getting thrown around of inside disc shield and landing on bottom of binder. Is this a bad "O" ring or something else? The rest of binder is dry. Has anyone else seen this seal go bad, I have 89,000 on this 02 D2

oil leak

Well if it is still leaking, it still has some oil left in it.
It sounds like a rear axle seal to me, unless it is brake fluid...
