Can somebody advice on how to replace a brake fluid on 2010 MB GLK350 without using a pressure system - just by classic method with a glass jar and clear hose? I do not have that system. Thank you.

Sorry - the new brake systems don't work that way - this article on W204 C-Class should help a bit to get a grasp on what is necessary - either pressure or vacuuum:

Just get a motive bleeder and do it dry way (i.e. to build up pressure). Super easy. Run 1-2L of new fluid.

Thank you for the article. It seems to be complicated since I should go over the procedure 3 times to make sure that there is no bubbles and then risk that the master cylinder can be damaged by pressing pedal too far toward floor. Again, I don't have that pressure equipment so to purchase it and enough amount of brake fluid may not be worthy versus the cost of repair shop would charge me ($120)
