The lever of a lay brake through тросовые draughts puts in action brake mechanisms of back wheels. As draughts the steel cable in a flexible, twisted braid is used. Deterioration of a lay brake is while in service insignificant. Usually adjustment of a lay brake is not required, thanks to work of system of self-regulation of brake disks.

Adjustment of a lay brake make at serviceable working brake system in following cases:

- After replacement of cables of a drive of a lay brake;

- After replacement скоб the brake disk mechanism;

- After replacement brake колодок or brake disks;

- At the big course of the lever of a lay course.

The prevention The trosovyj drive and all mobile elements of lay brake system should have an easy course, and back brake mechanisms of working system are adjusted.

Adjustment of a lay brake spend in a following order:

- Some times with force press a pedal of a brake and release it;

- Lower the lever of a lay brake in the bottom position;

- Raise and expose on a support a back part of the car;

Fig. 310. The Location of a regulator of a lay brake at the equalizer (it is shown by an arrow)

Fig. 311. Position рычажка a manual brake on a back brake support at adjustment of a lay brake

- Tighten an adjusting nut (fig. 310) near to the equalizer until рычажок a manual brake on a back brake support will not move from an emphasis (fig. 311). The formed backlash can make to 1 mm;

- Establish the lever of a drive of a lay brake in extreme top position and again lower it. Check up, whether wheels freely rotate. Overlays brake колодок should not rub about brake disks;

- Establish the lever of a drive of a lay brake on 3—6 clicks and be convinced that wheels in this case are not turned.

If traction cables of a drive do not provide a due tightness of all brake mechanism in this case adjustment of a lay brake spend in a following order:

- Completely ослабьте a regulator (fig. 310) a lay brake see until рычажки a lay brake on back brake supports will not depart back against the stop;

- Draw opposite each other two small lines — one on рычажке a lay brake, and another on a back brake support;

- Slowly tightening a regulator of a lay brake, watch for рычажками a lay brake which should rise. When the distance between labels will make about 1,0 mm, establish the lever of a drive of a lay brake in extreme top position that the tension of cables of a drive of a lay brake was levelled;

- Again check up position рычажков on both brake supports of back wheels. If it remains former tighten a regulator of a manual brake;

- Establish the lever of a drive of a lay brake on 3—6 clicks and be convinced that wheels in this case are not turned;

- Establish the lever of a drive of a lay brake in extreme top position and again lower it. Check up, whether wheels freely rotate. Overlays brake колодок should not rub about brake disks.
