Moving with a speed of 40 km/h, carefully tighten the parking brake so that easy braking was felt. At preservation of speed of the movement tighten a brake on one tooth and pass so about 400 m. Release a brake and let's it be cooled. It is recommended to repeat this process once in three months irrespective of replacement of a brake, so thus the rust which can be formed on a frictional surface, and wear products is removed.
