1. Place the car on an inspection ditch and "press" the rear of the car several times (force about 40–50 kgf) to set the rear suspension to the middle position.
2. Loosen the front bolt securing the regulator to the bracket.
3. Using the wire as a feeler gauge, adjust the bracket so that the gap between the drive lever and the lever spring is 2.0–2.1 mm.
4. To do this, move the drive lever by the lug. In this position, tighten the bolt.
If the pressure regulator is adjusted correctly, when braking from a speed of about 40 km/h on a horizontal section of the road with a hard surface, the front wheels should lock slightly earlier than the rear ones (this can be determined by an observer outside the vehicle). Otherwise, increase the gap (if the rear wheels lock up before the front ones) or reduce (if the rear wheels lock up much later than the front ones). After this, check the braking adjustment again and repeat it if necessary.
