Want to know what is the best brake fluid for your Mercedes-Benz? Using the correct brake fluid is more important than finding the best brake fluid for Mercedes-Benz.
While most vehicles require DOT3 or DOT4 brake fluid, Mercedes-Benz has developed its own special DOT4+ Brake fluid that has different specifications than DOT4 and DOT3 and is completely different than DOT5.
What is the best brake fluid for Mercedes-Benz?
The best brake fluid for your Mercedes-Benz brake system is printed on the cap of the brake fluid reservoir. Most likely is going to be DOT 4+ Brake Fluid.
If the Mercedes-Benz requires DOT 4+ brake fluid, do not use brake fluid from the auto parts store that says DOT 3, 4, 5, or 5.1.
DOT 4+ specifications are similar to DOT 4 brake fluid but with a higher boiling point to prevent brake fluid from vaporizing locks at high temperatures. Do not use DOT 5 or 5.1 fluids on Mercedes-Benz vehicles that require DOT 4+.

Wife’s 550CLS had a leaking front caliper and drained the reservoir to the point the that the add fluid light can on. I topped it off with Castrol DOT 4 not knowing I needed 4+. Now every caliper leaks. I’ve got my fingers crossed that a flush will fix it.
