Brake pad lining fell off of OEM pads!!!
After a few pumps the pedal got firm again and braking returned but with a terrible grinding metal-to-metal sound.
I carefully drove, via local low speed roads, to my MB-indy and as it turned out my front pads were almost gone without a wear-warning(!) and one pad on the driver side lost it's last bit of lining. Upon removing the passenger side pads one of them also has a loose lining...
I have no idea if this CAN happen with worn pads but if this happened on the freeway there would be no time to react and I would have hit the car in front of me at full speed!!!
