[F11MSport]

Hi,this is my first thread so would like to say hello to everyone and ask for an advice.
Few weeks ago I noticed a difference how brakes in my f11 started working . Brake pedal takes pretty high and is quite hard when pressing (is not soft or flexible as it was before). Also noticed that braking distance is longer than used to be and when I want to completely stop a car,there is a noticeable jerk when car coming to stop. There in no soft stopping.
I changed a brake pads with original bmw parts and skimmed front discs just to take these out of equation.
I am dropping my car next week to the bmw garage to see if they can find anything but would appreciate if someone could put some light on this issue.
Thanks
