I just bought a used badger and I am trying to change the front brakes, but I not sure how to get to them. I can get the nut and cotter pin off but that is all I can get off. This is the schematic I have off my bike and I do not see anything but maybe a bearing and seal the holds the hub on. I can not get the hub off. I appreciate any information on this.  

the hub should slide off.
if not then you may have some issues with the wheel bearings.  

Thanks I did get the hub off by beating it off. It was either a problem with the bearings or that the brake pad had feel off and was wedged in there. Now I have to get the bearings replaced. I hope to have that done this week. The shop in town does not open till Tuesday, but I will be there when the open and hope they have the parts. Also i believe the bearings are pressed in, so I will get them to do the work.
