Unscrew fluid reservoir cap, stick in probe, press button, see pretty
light/s, determine there is stuff all water in fluid, put cap back on,
clean tester, have beer after working so hard.
Roger method: take car and credit card to dealer, hand over both, have
cup of latte whilst browsing complementary magazines, receive car, drive
off. OK to be fair I suspect that the modern brake system in a Merc is
not as simple as the flint stone models most of us have.
Now before you get all, "but the fluid in the calliper could be full of
water", consider that without disassembling the calliper (or using the
below method) you will always have old fluid in the caliper because the
bleed nipple is a the top and not the bottom of the calliper.
So when someone says they changed the brake fluid, they only changed
~60% of the fluid.
Another thing to consider is that when MB or others say that the fluid
should be changed every two years they work on the worst operating
conditions, with a great deal of safety margin. Do they care how much
people spend on unnecessary fluid changes? Nope.
Now to do a best job on changing brake fluid, it should be changed when
the brake pads are replaced and the calliper piston is pushed back into
the cylinder, that's what I do. The advantage of this is that you can
open the bleeder valve and push all the old crappy fluid out and not
back up into the system.

But brake fluid is so cheap (DIY, that is) and where and how would you take
the sample? Does each caliper pee in a cup?
