2, it has no idea what pads it has so doesn't both with the warning light at all. The first sign you get of worn pads is it wearing through to the metal and destroying the discs! That is assuming, of course, that you rely on the warnings to tell you when the pads are worn.

It uses the servo in the motor to determine how much the piston moves by when it applies or releases the parking brake, but it doesn't know the absolute position of the piston, hence why you have to tell it the pad thickness so it can calculate the change from the piston movement.

Is this a sign for the future?
Mikki knows something about D3's
Is there hope for the lesser ones amongst us?
If I don't fall of my perch could it be that my D4 could feel the touch of her gentle hands?
