For this purpose carefully tighten the parking brake at speed of 40 km/h so that brake action was slightly felt.
Keeping speed of movement, tighten a brake on one tooth and pass 400 more m. Release a brake and let's to it be cooled. The rust which can be formed on a frictional surface, and wear products thus is removed.
