I have had a clicking at times when turning right in my '84 300 SD. Sometimes its more noticeable than other times. Well, when taking off my front wheels to do my shocks, I think I found the culprit. There is metal component that is fairly thin that is part of the brake structure, but is behind the rotor. It is circular. On my right side it has some give (and it clicks when I push it and pull it!), but it doesn't on any other wheel.

Problem is, I don't know what it is called and how I would replace it. Has anyone seen this? All 4 of my brakes are in need of a replacement and I would like to replace this part as I do my front brakes. Thanks.
