After the first 2500 km and at TO-2, and also if the equipped car, when braking on a dry hard surface, the rear wheels are blocked earlier than the front wheels or much later, you should make sure that the regulator is adjusted correctly
The regulator should be adjusted in the following order:
Fig. 1. Pressure regulator
- disconnect from the bracket 23 (see Fig. 1) on the rear axle the lower end of the rack 24 of the regulator, unscrewing the axle nut 5 for this;
- unscrew the lock nut 10 by a few turns and, turning the adjusting bolt 11, set the distance С:
- for GAZ-2705 and GAZ-2705 "Combi" - 13-17 mm;
- for buses - 28-32 mm between the axle 6 and the hole in the bracket 23;
- tighten the locknut, keeping the adjusting bolt from turning;
- fix the lower end of the rack on the rear axle bracket.
It is necessary to check the correct adjustment of the pressure regulator by braking until the wheels lock on a horizontal section of the road with a hard dry surface at a speed of 50-60 km / h.
With a properly functioning and properly adjusted pressure regulator, there should be some advance of the front wheels locking relative to the rear ones during effective braking.
If the rear wheels are blocked before the front ones, then after unscrewing the lock nut 10, unscrew the adjusting bolt 11 by half a turn and lock it again.
If the front wheels lock much earlier than the rear wheels, then turn the adjusting bolt half a turn.
After performing the above operations, check again the setting of the regulator by braking on the road.
It should be remembered that if the rear wheels are blocked ahead of time, the car may skid, and if the front brakes are blocked much earlier than the rear ones, then the car may lose control of the car, especially when driving on slippery roads.
