SL/R231: Replacing rear red brake caliper cover




eBay Mercedes Caliper Plates
They look like a quality product, just make sure to compare pin spacing to get the correct one as there are different sizes. (not affiliated with seller)

yeah, that’s the one




Though tough to bend, you can bend the teeth to give the clip more “bite”.
Good Luck




The goal is for the directional teeth have to bite both the outer diameter of the dowel and inner diameter of the caliper bore.
Another issue is the cover is made out of very soft aluminum. They’re kind of a “one time use” part. So pulling them in and out of the brake caliper can eat into the soft aluminum dowels on the cover. You may have to bend the tabs a little to get them to bite more, but try to avoid pulling them in and out if possible.
I’ve had the best luck by putting the clips either half way in the bore, or halfway on the dowels, and THEN pushing the cover on. That has a tendency to seat the cover with the clips midway, biting the maximum amount. The goal is to get the clips to sit halfway on the dowels and halfway in the bore. The clips will not really bite into the cast iron as much as they bike into the soft aluminum cover. The way they are right now, the right one appears to be sitting too high on the dowels.
In reality, there should be no force pushing on the cover when it’s on the car. I think the clips/dowells sometimes corrode causing them to fail. The other issue I’ve run into is techs using caliper spreading tools to compress the piston, but mistakenly using the cover to push against. Then once they realize they f***ed up, they just push it back in haphazardly. Of course it takes a while before the cover falls off and/or the owner realizes it….
Hope that makes sense.
Good Luck.
