Hard brakeing without touching brake

[davidstan]

Hello all, first post! I have owned Club Cars for 12 yrs or so and never had this issue come up and wondered if you fine people may lend some guidance. When travelling along the road my right brake will seize up or the axel seizes just as if i slammed on the brake. So much so it leaves rubber behind. Inspecting the brakes i dont see that they are the problem. Could it be something stuck in the axel. Is this a common issue? Thx for any help!
