The drum has to be removed rather freely, in case of difficulties, accurately tap it a hammer with soft brisk, or screw couple of bolts of M8 in carving openings.

Take a rubber cap from a brake board, pass a screw-driver throughout the opened opening and take away it the self-regulator lever from an adjusting asterisk. The second screw-driver rotate an asterisk until the drum completely is not released. |

Authors of the present manual recommend to make a pro-point of drums regardless of their state for the purpose of any removal of defects and elimination of ovality. If the pro-point of a drum cannot be made without violation of requirements to the maximum admissible internal diameter (it is beaten out on a drum, it is necessary to make its replacement. If it is not possible to make a pro-point of drums, at least, carefully smooth out them working surfaces a fine-grained emery paper. |
