I'll have to check the brakes again, but I don't remember seeing a dust cover. I may have tossed it at some point in the past 10 years. Are you talking about the thin metal shims that the pads are supposed to slide on? If so, yeah...them things were tossed a LONG time ago.
I can't be sure what torque spec I used on the hub nuts, but I'll be checking that soon. Normally I set torque to f*ing tight and roll with it.
Thank you for your guidance, man.
