I did a search, but found no answer. I have been looking into all these rear disk brake web sites, and was wondering what holds the axle in place, The caliper? If so, is that strong enough. Originaly its held on with the pressed in bearing, and retainer and c-clip, and thats attached to the drum assembly and now it seems nothing is holding it on. Could anybody tell me how the axle is held on? Sorry for the long post.
