Incorrect adjustment of the pressure regulator actuator can cause the vehicle to skid or pull to the side during braking, reducing braking efficiency.
You will need: key «at 13», wire with a diameter of 2.0–2.1 mm.
1. Install the car on the inspection ditch and squeeze the rear of the car several times with a force of about 400–500 N (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, align the bracket so that the clearance between the drive arm and the arm spring is 2.0–2.1 mm.
4. To do this, move the drive lever by the ledge. Tighten the bolt in this position.
5. If the pressure regulator is correctly adjusted, when braking from a speed of about 40 km/h on a level section of paved road, the front wheels should lock up a little earlier than the rear (this can be determined by an observer outside the car). Otherwise, increase clearance (if the rear wheels lock before the front) or reduce (if the rear wheels lock much later than the front). Then recheck the brake adjustment and repeat if necessary.
