If, when braking the car with a parking brake, lever 1 (see Fig. 1), when a force of 600 N (60 kgf) or more is applied to it, is fixed on the extreme upper teeth of the sector, then the drive should be adjusted in the following order:
Fig. 1. Parking brake system
- set the drive lever to the lowest position;
Fig. 2. Rear wheel brake
- remove the plugs 20 (see Fig. 2) in the brake mechanisms of the rear wheels. Using a 17 mm asterisk wrench, loosen the nut securing the eccentric of the adjusting mechanism of one of the brakes by 1.0-1.5 turns;
- eliminate the gap between the expansion link 11 and the lever 12, for which, with a special tubular wrench 9 mm in size, turn the bolt 25 of the eccentric in the direction indicated by the arrow until resistance to rotation is felt, which is associated with the expansion of the pads (beginning pad movements can also be determined through viewing windows in the shield);
- tighten the eccentric fastening nut to a torque of 24-35 Nm (2.4-3.5 kgf m) in the position where the pads begin to expand. At the same time, using a 9 mm key, you should keep the eccentric bolt 25 from turning;
- similarly adjust the position of the expansion link 11 in another brake mechanism;
- install plugs in the brake mechanisms;
- check the presence of gaps between the tips of the cables 5 (see Fig. 1) and 8 and the depressions on the equalizer 9.
The gaps are eliminated by tightening the nuts securing the cables on the bracket 4.
Adjustment should be made in such a way that after adjustment the equalizer is at a distance Б from the front wall of the bracket and perpendicular to the longitudinal axis of the vehicle.
With a correctly adjusted parking brake drive, the drive lever under a force of 600 N (60 kgf) should not move more than 15 teeth of the locking mechanism.
