Lay brake



Process of adjustment of a lay brake depends on a design of a working brake of back wheels. For drum-type and disk brakes it is distinguished.

For drum-type brakes - to the middle of 1995 of release

Adjustment of a lay brake is provided with the mechanism of self-installation of a working brake. Вытягивание a cable of a drive of a brake can lead to increase in a course of the lever of a brake that will demand corresponding adjustment. For installation brake колодок in a starting position it is necessary to press a brake pedal so that the mechanism of automatic installation колодок any more did not click. For adjustment carrying out two persons are required.

1. Lift and establish on supports a back part of the car.
2. Completely release a lay brake.
3. Ослабьте a nut (1) adjusting draughts also tighten an adjusting nut (2) to pull a cable. Thus brake колодки should concern slightly a brake drum, i.e. the brake only starts to work.
4. Three-four times cock a lay brake and check up, that wheels have been clamped, if the brake lever is established on the fourth tooth of sector.
5. In this position tighten a counternut the moment of 12 Nanometers.
6. Release a lay brake and turn wheels. They should rotate freely. Check up rotation of both wheels since at rotation of one wheel another can заедать.
7. Again move the lever of a lay brake on 4 teeth and check up, whether wheels are clamped.
8. Inspect some times, tightening and releasing a brake.
9. If adjustment is spent successfully, lower the car on the earth.
10. Check up brake action on a bias.

For a disk brake - from the middle of 1995 of release

Here the backlash between brake колодками and a disk drum from the interior of a drum is regulated. The specified backlash should be adjusted before adjustment of a tension of a cable of a drive.

1. Lift and establish on supports a back part of the car.
2. Take out a rubber stopper from an aperture for adjustment from an underside of a brake board in a place shown on an illustration.
3. Insert into an aperture a screw-driver and move downwards a castor of an adjusting bolt so that brake колодки concerned a drum.
4. From this position, gradually rotating a castor, result a drum in a motionless condition.
5. Turn a castor of an adjusting bolt in the opposite direction so that the drum had possibility to start to be turned. Usually the castor on 7 - 8 teeth for this purpose is necessary to turn on back.
6. In summary turn both wheels, having convinced that brake drums are not clamped колодками.
7. Adjust a tension of cables of a drive of a lay brake in the way described above. The difference in this case consists that the brake lever should keep wheels at its position between 5 and 7 teeth of sector.

For drum-type brakes

The drive consists of two cables which fasten on the one hand to brake колодкам back brakes and on the other hand to the equalizer located under the bottom of the car. Cables are replaced in steam.


1. Lift and establish on supports a back part of the car.
2. Measure by a ruler length of the acting carving end of adjusting draught.
3. Write down the size and turn away an adjusting nut.
4. Disconnect both cables from the equalizer.
5. Remove brake колодки and disconnect from them cables as it is described above.
6. Remove flat-nose pliers on each cable a spring clip from an underside of a brake board (in a clip point to a board).
7. Disconnect cables from directing on a floor and a suspension bracket of wheels. For this purpose probably it is required to unbend holders. Remember the scheme of a lining of cables.


Installation of cables is made in sequence, return to removal.

1. Lay cables.
2. Establish brake колодки according to the description resulted in Section 3.
3. At assemblage maintain the size of an acting part of the adjusting draught, received earlier.
4. Adjust a lay brake as it is described above.
5. Lower the car on wheels.
6. Establish wheels and fix them.

At disk brakes

Cables are replaced to description similarly resulted above. The difference consists that not brake drums, and disk here act in film.


1. Measure the acting carving end of adjusting draught.
2. Turn away a nut and remove the equalizer.
3. Disconnect cables from drive levers on supports.
4. Disconnect cables from directing on a floor and a bridge arm.


Installation of a disk brake is carried out in sequence, return to removal. Pay attention to a correct lining of cables.

1. Bolts of fastening of holders of cables tighten the moment of 9 Nanometers.
2. Screw adjusting nuts, having provided the size received earlier.
3. Adjust cables as it is described above.
