With back brake disks the emergency brake works at models irrespective of hydraulic brake system. Thus brake shoes of drum type are used, and as the brake drum the internal part of a brake disk is used.

Surely make replacement of all blocks even if the limit of wear were reached by one block.

During the work of brake shoes brake dust which contains asbestos, unhealthy is formed. Therefore when cleaning brake shoes do not use compressed air and do not inhale dust.
