For brake disc service and repair, remove the wheel and tire assembly and then lift the caliper in place. After that, remove the retainers holding the disc to the hub studs and remove the disc from the hub. Should the disc shield need assistance, the first thing to remove is the front hub and bearing assembly. Before setting the disc onto the hub, first clean off any protective film on its surfaces, then assemble everything in the order: hub, disc, caliper and wheel and tire assembly.
