Brake Lining Sensor: Notes
WARNING: This page is about a different car, the 2005 BMW 545i and 2004 BMW 545i. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If a brake lining sensor that has already been ground has to be replaced, even though minimum brake lining thickness has not yet been reached, it is necessary to file the new sliding contact down to the same length as the ground sliding contact.
