As for the battery there's plenty of youtube vids on parasitic current drain.
or call in an auto spark.
As to the brakes they need looked at by a tech.
I know you state the pads are relatively new but I've seen some eaten in less than 6 months.
Merc pads are fitted with "screamers",
little metal tabs that run against the disk when the brakes are applied.
General idea is for a warning of impending brake failure.
