my 328i was parked in a parking garage.
everything was fine when i left it  there and when i was drivng before .
no spongy brakes ect.
i get a call next day there was an accident when an attendant drove it.

they claim the brakes didnt work , and the brake fluid light is on.
i go to inspect, yes its a little low and the light is on.
i see no leaks around the wheels BUT
there  is fluid on top of the brake reservoir and along the sides.
also in spots where u dont expect it ( on the strut)
metal pipes from reservoir OK.

the fluid was low but not much. could still see it in the reservoir.
added fluid and all ok.(didnt take much)
havent had a mechanic inspect it yet.

BUT

did the garage guy put a rag in the reservoir and take the fluid out
to cover his mistake ?
looks like a 15 mph hit.
front quarter panel  pushed in and bumper pushed in.
whould that make the fluid splash ( doubtful) ?

cant see master cylinder.
obviously mechanic will look at it.
