There are about 3 different types of calipers used on the MB's, Bendix and ATE are almost the same except the Bendix type uses a heat shield on the pad side of the pistons. The third type, don't remember the name, is quite a bit different but I doubt you'll have it. The other thing to be aware is that the pistons are right and left sided and have to be re-assembled in a particular way. The raised ridge on the pad side of the piston needs to be turned in a particular direction. There's a special tool with a particular angle that you place on the caliper to point the ridge in the right direction. You can make the tool yourself as well if you know what it looks like.
Also the calipers are difficult to hone since the shop manual specifically states not to split them appart.
