In the drum-type brake mechanism two are located against each other
колодки — forward and back, established on pistons of the wheel brake cylinder and fixed by a fixing plate near to the bottom coupling spring. Both
колодки are pulled together by the bottom spring. By pressing a
pedal of a brake pistons of the wheel cylinder move outside, pressing
колодки to an internal wall of a brake drum. At wheel rotation forward the lobby
колодка becomes self-braking. At wheel rotation back back
колодка becomes self-braking. Force from brake
колодок is transferred to a fixing plate through a basic plate on an axis flange. Backlash adjustment is made automatically irrespective of application of a brake and deterioration of overlays
колодки. Do not change position
колодок which have been already used. It can affect function of self-regulation and to become the reason of increase in a course brake
колодки.
