moinzen, had noticed yesterday, that it smells like burnt brake lining and that the rear right rim was warm. Today, the brake was not really solid but already heavy, after brake operation it releases only cumbersomely. So wheel off, brake caliper lower screw loosened and folded up, the piston cuff is damaged. Everything already clean and smooth made and now is good again. But that does not last long and then it starts again. So in the EPC check, the repair kit (A000 421 1248 with piston, seal and cuff) costs around 100 euros, the whole saddle about 300. And then I tried it again in the bay for an exception, and what do I find, tens of inexpensive brake calipers for the G-Class, also at the rear, which cost only from 60 euros. For front with two pistons still under 100. also from Bosch. Even repair kits. Only for my model 270 cdi is there nothing. Can that be, after all, that was a volume model for the AMG? is not the saddle, I can see that, but maybe pass the overtaking kit, of which I only need the cuff. The AMG piston has 42mm diameter. Does any of you know if it could fit with the 270er? The part number of the 270-brake saddle is A000 420 1079.
