Check Brake Fluid Level

[2017 Mercedes Benz C350E]

Hello there again

I was driving back home until suddenly a message popped up in the central screen stating l. Check brake Fluid level with a little symbol which the. Disappears in a couple of seconds.

Now with the message being simple to understand the only thing that concerns me is the fact that because I replaced the electronic handbrake with the brake fluid about a month ago or 2

I ponder on why this message has popped up it is no way that brake fluid levels can be so drastically low in such a short period of time


Can someone please help me figure this out?

Check master cyl. It may be coincidence but when pads ready for change fluid level may drop enough to trigger level warning.. If the case be aware that topping at this stage not always the answer as pushing caliper pistons back for new pads will often expell the excess over ur paintwork.
If that's not the case retrace the work you previously carried out. Look for traces of b fluid on garage floor. Investigate anything noted and check all fluid tanks
