Drum brake mechanism
The rear wheels should not turn when the parking brake lever is tightened to 4 or 5 notches. Repeat tightening the parking brake lever approximately four times. To check the wheel braking, the car is placed on jack stands. If the parking brake action requires adjustment, proceed as follows.
1. Tighten the parking brake lever to the fifth tooth of the sector.
2. Place the rear of the vehicle on jack stands.
3. Loosen the outer nut on the parking brake cable equalizer located under the vehicle (see illustration).
8.3 Adjusting the tension of the parking brake cable. After unscrewing nut 2 on the cable equalizer, tighten the adjusting nut 1 so that friction noise is felt when turning the wheels
4. Tighten the second nut located underneath it until you feel a certain resistance and friction noise when turning the wheels.
5. Replace the outer nut on the cable equalizer.
6. Check the operation of the parking brake. To do this, apply the parking brake to the five notches of the sector and make sure that both rear wheels are locked.
7. Release the parking brake and check that both rear wheels rotate freely without any extraneous noise.
8. Lubricate the cable equalizer with multi-purpose grease.
Disc brake mechanism
Locking the rear wheels with the parking brake should occur in the same way as with drum brakes. Adjusting the tension of the parking brake cable is performed in the same way as described above (see illustration 8.3).
However, before adjusting the tension of the parking brake cable, it is necessary to adjust the position of the brake pads in the inner recess of the disc.
9. Release the parking brake lever and remove the bolts securing both rear wheels.
10. Place the rear of the vehicle on jack stands.
11. Turn the brake disc so that the hole plug on the outer side of the brake disc is facing down. Grasp the plug with pliers and twist it a quarter turn to remove it.
12. Install the brake disc as shown in the illustration. In this position, the hole on the brake disc is located opposite the brake pad adjusting gear.
8.12 Adjusting the rear wheel disc parking brake. Insert a screwdriver into the hole on the brake disc. Depending on which wheel mechanism is being adjusted, the screwdriver should be moved up or down
13. Insert a screwdriver into the hole on the brake disc. The disc may need to be turned slightly to allow the screwdriver to engage the adjustment gear.
14. Rotate the adjusting gear until the brake disc locks. When working on the left rear wheel, the adjusting gear must be turned upwards, and on the right wheel - downwards.
15. Rotate the adjusting gear in the opposite direction. The offset is approximately 6 gear teeth. This ensures the required clearance between the brake disc and the brake pads.
16. Replace the hole plug on the brake disc. To do this, turn the brake disc so that the hole into which the screwdriver was inserted is at the bottom. After installing the plug, use pliers to turn it half a turn until it locks into place.
17. Adjust the parking brake cable tension as described above. After completing the adjustment, install the wheels and tighten their mounting bolts to a torque of 100 Nm.
Replacing the parking brake cable
When replacing the parking brake cable, the brake pads must be removed. The cable should be lubricated with a universal lubricant before installation.
After replacing the cable, the parking brake must be adjusted by following the steps listed above.
