When my C320 was at the dealer ten days ago for replacement of the hvac panel due to a sticky button, I had forgotten to verify with the tech that DOT4+ brake fluid was what is now used by MB.I needed to know because when I replaced the brake pads last month I did not replace the fluid that I had bled from the calipers when pushing the pistons back. So when I stopped by last week to ask him, he asked why I wanted to know. When I told him, he went to his cabinet and pulled out two liters of MB branded DOT4+, saying that should be enough. No charge.
Well, it was. What I needed was about five tablespoons of it. Turns out the MB brake fluid is manufactured by CCI Manufacturing in Illinois, a Japanese owned corporation which has been making brake fluid since 1949 in Hiroshima. Known as Chuo Chemical Industries in those days. RLE
