To assemble the axles with the new disc brake hardware first place the axle retainer, which will require some minor clearancing of its ID to fit) over the axle, then fit the Vintage Venom bracket next. In this photo, the axle retainer is in place but is hidden under the caliper mounting bracket. Make sure the recessed holes for the caliper face toward the outside of the axle and then press on the bearing and bearing retainer. Make sure everything is in the correct order and oriented correctly before installing the bearing and bearing retainer because a mistake here will require cutting off the new bearings and the purchase of another set. Now is a good time to install new axle seals as well.
