Maintenance work
The piston pushes the wearable brake lining so far that it is only a fraction of a millimeter from the brake disc. Therefore, brake pedal free play is not a guideline for determining front brake pad wear. Even in vehicles with a brake pad thickness control system, you should not forget an additional visual check, and not only when traveling on vacation.
The minimum thickness of the lining, including the carrier plate, is 8 mm. The carrier plate itself, i.e. the metal part on which the overlay is glued has a thickness of about 5 mm.
The check is made with the wheel removed.
Attach a ruler to the overlay and measure as shown in the photo on the next page. To check the outer lining, pry the brake caliper out with a large screwdriver.
