Calculation of remaining driving distance in km

Measure the thickness of the brake pads.

Find out the driving distance since the last change.

Read off the calculated remaining driving distance at the point of intersection for driven distance and brake pads thickness in the table.

Measure the thickness minus 2 mm multiplied by driven distance since the previous change. This value is divided by the original measurement (14 mm) minus the measurement in mm.

Example:  The thickness is 7 mm and distance driven since last change is 25,000 km. Giving approx. 17,800 km remaining driving distance. Replacement is recommended at values below 30,000 km, in bold in the table. 

Values in the table are approximate calculations assuming that driving conditions are met during the entire service life of the brake pads.
