The parking brake must hold the vehicle on a 25% slope when the parking brake lever is moved 15-20 teeth (clicks) of the ratchet
To check the correct adjustment of the parking brake, find a flyover or loading ramp near the parking lot of your car with a height of H \u003d 1.25 m with an entrance length of L \u003d 5 m. This ratio corresponds to a slope of 25%
In the absence of such a ramp for a simplified check of the parking brake, place the car on a level area.
Place the shift lever in neutral, fully raise the parking brake lever.
Get out of the car and try to move it.
If you succeeded, you need to urgently adjust the parking brake actuator
Adjusting the parking brake actuator
Lower the parking brake lever to its lowest position.
Pry off with a screwdriver and remove two plastic plugs of the brake shield (the wheels have been removed for clarity).
Using the “17” head, we loosen the eccentric nut of the brake mechanism by 1–2 turns.
With a long “9” head or a special tubular wrench, turn the eccentric bolt until resistance to rotation is felt, which is caused by the expansion of the pads.
The start of the block movement can also be determined through the viewing windows in the shield.
Using a “17” head, we tighten the eccentric nut with a torque of 2.4–3.5 kgf.m.
At the same time, we keep the bolt from turning with the “9” head.
Similarly, we adjust the brake mechanism on the other side of the car and install plastic plugs in the brake shields.
We eliminate the backlash between the ends of the cables and the troughs on the equalizer, for which: with two “24” wrenches, we loosen the nuts for fastening the cable sheath (Fig. 5) and, moving the nuts along the threaded part of the sheath, we achieve the elimination of the backlash between the cable end and the trough on the equalizer.
Similarly, we eliminate the backlash at the other tip of the cable.
Tighten the locknuts of both cables. In this case, the equalizer bar must be perpendicular to the longitudinal axis of the vehicle.
Using a ruler or tape measure, measure the distance between the equalizer and the front wall of the bracket. It should be within 144–150 mm.
If necessary, adjust the position of the central cable in the same way as adjusting the rear cables.
If after that there is a play between the tips of the rear cables and the equalizer, repeat the adjustment described above.
With a properly adjusted drive, the parking brake lever should not move more than 15 sector teeth (clicks).
