My dust shields are so rusted that I can no longer mount my parking brakes.I inquired into replacing them, however that meant removing the hubs, the local shop who quoted me said by doing so you will likely need new wheel bearings.Firstly, remove your dust shield, it is held on by two 10mm bolts, and 2 very thin 16mm bolts.I used a wire brush to clean off the rust, and some liquid wrench to loosen them. You will not be able to use a socket wrench, because it is too big to fit in behind the hub flange.I should mention that the two 16mm bolts are so damn thin, that your wrenches will likely not be able to grip onto them.Once I removed the old dust shield, I then took my new dust shield and I cut an opening large enough to slide over the hub, while still keeping the mounting holes intact. See pics for details. Notice I spray painted the dust shield, because I damaged the paint when I cut them and I did not want them to rust prematurely.
