if they are the same setup as the 123s (maybe not) also replace the brake struts that go from the arms to the brake discs (or at least the bushings there)

When I replaced this part on my 123 I also wire brushed the arm (top and bottom ) and sprayed 3-4 coats of rustoleum on it so I wouldnt have to do this again.
