Removal, inspection and installation of the rear brake drum

To do this, pull out the small rubber grommet located near the center of the brake shield and insert a screwdriver into the small hole. After that, you can turn the ratchet of the regulator so that the pads go to the lowest position (see fig. 5.2, a, b). Install the rubber bushing.
