But in a post before yours, it's been stated it isn't the parking brake's shoes inside the rotor hub, but the rotors binding with the main brake pads with rust... Also, even the manual (not to mention my experience with previous cars using this kind of parking brake) suggest one should use the parking brake as often as possible, or the linkage and all other moving parts will corrode, get dirt etc. resulting in the whole mechanism losing effectiveness... And when are we supposed to use the parking brake "often", if not during actually parking the car? Plus, how often do we park it on a sloppy surface?

Considering all the above, I guess I've developed a habit (almost a unconditioned reflex) to engage parking brake when storing the car in my garage...

On another note: the rotors are so badly rusted after I stored my M235i for several days after washing it that I wonder whether they gonna shine again just after normal brake usage over several hundred kilometers, or if I should disassemble, clean and perhaps even grind/polish them...
