My merc Eclass WDB 221 046 -it appeared Brake Service on the display.. ive checked the brake pads are still thick and the brake fluid are at the right level, i even look at the brake wear sensors nothin wrong ... could it be beacuse of the brake booster? or was it because of the spare batter under the air condition cleaner cover on the front left of the engine ?

what should i do ..?

have you tried to disconnect the battery and see if it comes on again.
